A: The slurry concentration is one of the main factors affecting the flotation index. During the flotation process, the slurry concentration is very low and the recovery rate is low, but the concentrate quality is high. As the pulp concentration increases, the recovery rate also increases. when the concentration was increased to an appropriate level, and then increase the concentration, but decreased recovery, in addition, have a direct impact on the plasma concentration of the flotation complex process of inflating the amount of flotation machine, flotation reagent consumption, processing power and flotation time.
2. The relationship between the pH of the pulp and the flotation index:
Answer: The pH of the pulp generally refers to the concentration of hydroxide ions and hydrogen ions in the slurry. In different acid-alkaline solutions, the effect of the agent is different, the floatability of the mineral surface is also different, and some agents are in a certain acid. The base value has a strong ability to capture, while the other has a strong ability to select. Each agent has an optimal acid-base zone.
3. What is the pharmaceutical system and how does it affect the flotation?
A: The pharmaceutical system, also known as the prescription, refers to the type and quantity of the agent added during the flotation process, the general name of the dosing place and the dosing method. It has a significant impact on flotation indicators.
For a certain kind of medicine, there are several kinds of medicines, and their performances are different, such as collectors , some collectors have strong performance, but the selectivity is poor, and the other is just the opposite, the collector performance is strong. The possible recovery rate is high but the quality is poor.
Under a certain range and certain conditions, increasing the amount of collector and foaming agent can increase the flotation speed and improve the flotation effect, but the excessive dosage will cause the flotation operation process.
The determination of the dosing location depends on the action, use and solubility of the agent, such as the conditioning agent, in the ball mill to eliminate harmful ions that cause activation and inhibition.
The dosing method is divided into one dosing and batch adding. The former can increase the initial speed of flotation and is beneficial to increase the flotation index, but for the insoluble in water, it is easy to react in the pulp and fails, and some Poorly selective agents should be taken in batches.
4. What is inflation and its effect on flotation?
A: Inflating is to send a certain amount of gas into the slurry, and make it diffuse into a large number of tiny bubbles, so that the hydrophobic minerals are attached to the surface of the bubble, strengthen the aeration effect, can improve the flotation speed, save water and electricity. And the pharmacy, but the excessive amount of inflation will entrain a large amount of slime machinery into the foam product, which will cause difficulties in sorting, and ultimately it is difficult to ensure the quality of the concentrate.
5. What is the purpose of slurry mixing and its impact on flotation?
A: The purpose of slurry agitation is to promote the uniform suspension of the ore particles in the slurry in the tank, and to make the air diffuse well, resulting in a large number of active bubbles. For strong agitation, it is beneficial for flotation, but excessive bubbles will occur. Mergers, quality of concentrates, increased power consumption, mechanical wear and other shortcomings, suitable aeration and agitation should be determined by experiment according to the type and structural characteristics of the flotation machine.
6. The relationship between the length of flotation time and the beneficiation index:
A: The length of flotation time directly affects the quality of the indicator. The flotation time is long. The recovery rate of useful components in the concentrate is high. However, the grade of concentrate is reduced and the flotation time is short. It is beneficial to improve the product grade, but it will make The tailings grade is elevated.
Generally, when the useful mineral is good in floatability, low in content, suitable in ore size, low in pulp concentration, fast in action, and strong in aeration and agitation, the required flotation time is short.
7. What is the effect of temperature on flotation?
A: Temperature is also a factor affecting the flotation effect. The temperature affects the dispersion of the agent in the slurry and also affects the floatability of the mineral. For the fatty acid collector, the temperature of the slurry plays a role in the dispersion of the agent and the activity of the mineral. Great effect.
In general, for the flotation of sulfide ore, is not sensitive to changes in temperature, in the range of climate, temperature changes have little effect on the float tank, antimony float, and therefore the temperature is not a requirement.
For tungsten floatation, the change of temperature has a great influence on the index. The temperature of white tungsten flotation requires more than 12 °C (saponified oleic acid), so heating is required in winter, and the temperature of processing flotation is required to reach °C.
8. How does the flotation machine work?
Answer: The slurry is fed into the impeller by the feed pipe. The centrifugal impeller is thrown into the groove by the centrifugal impeller, so a negative pressure is formed on the cover plate, and the air is automatically introduced by the intake pipe. The sucked air and the fed slurry are in the impeller. The upper mixing is again thrown into the trough, which in turn generates a negative pressure to draw in the air, so that the slurry is mixed in the upper part of the impeller and thrown into the trough, thus generating a negative pressure to draw in the air, thus continuously. The drug-applied slurry is brought to the surface by bubbles to form a mineralized foam layer, which is scraped off by the scraper. The non-floating minerals and gangue enter the next flotation cell through the gate on the side of the trough. Inside, the slurry surface can be adjusted according to the gate, and the slurry is circulated in the machine.
9. What is the structure of the impeller type mechanical stirring flotation machine?
Answer: The flotation machine consists of two units per two tanks. The first tank has a suction pipe for pumping slurry. There is an intermediate chamber between the first tank and the second tank. The slurry is connected at the lower part. At the lower end of the vertical axis, the upper part of the straight shaft is provided with belt wheels, which are driven by the motor to rotate rapidly by the V-belt. The slurry that is sucked into the air through the introduction tube is adjusted by the gate. The impeller has a small wheel cover and a middle air tube. The lower end of the intake pipe is provided with a feeding pipe, and the feeding pipe is coupled with the bearing box, and the rotating auger can control the size of the circulating hole of the slurry, thereby adjusting the amount of circulating pulp.

10. What are the basic functions of the flotation machine?
Answer: In addition to the continuous and reliable work, long life, easy maintenance, low power consumption and simple structure, the flotation machine should also have the following special functions: 1. Inflation; 2. Stirring; 4. Pulp surface inflating The amount can be adjusted frequently.
11. What is the significance of flotation?
A: The flotation dominate various beneficiation methods, broad range of applications, not only can handle non-ferrous metal minerals, can also handle non-metallic minerals, but can also handle black metallic minerals such as hematite, manganese, titanium Iron ore.
The flotation has a high sorting rate. It can select very poor ore as a high-grade concentrate, thereby expanding the scope of resource utilization and turning some low-grade deposits that were previously considered undevelopable into valuable deposits, flotation. It is particularly effective for the treatment of fine-grained ore, which solves the problem of recovery of useful components in many fine-grained ore particles. Flotation can also improve concentrate quality and high recovery rate.
12. What is the relationship between the solid phase, the liquid phase and the gas phase in the flotation?
A: The solid phase is the finely ground ore; the liquid phase refers to water and solution; the gas phase refers to the dispersed bubble.
Characteristics of solid phase: There are many types and forms of minerals. There are often several kinds of minerals and gangues. The shapes are square, cylindrical, flake and irregular angular. The particle size range is wide, the particle size and surface area are large.
The characteristics of the liquid phase: water and solid powder in the slurry and gas phase, the ore often contains various soluble salts dissolved in water, industrial natural water also contains soluble salts, dissolved in water, oxygen, nitrogen and Carbon dioxide, etc., therefore, the water in the flotation slurry is not simply water, but a solution.
Gas phase: Air is a finely dispersed bubble in the slurry, which can carry the ore particles floating up, and can also be repeatedly dissolved and precipitated in the pulp. The oxygen in the air has a great influence on the floatability of the mineral.
13. What are the criteria for judging the minerality of minerals?
A: The standard commonly used to judge the floatability of minerals is the wettability of mineral surfaces, that is, hydrophilicity and hydrophobicity; the minerals that are wetted by surface water (hydrophilic) think that this mineral is difficult to float or not. Floating, if the mineral surface is not wetted, it is considered to be easy to float or float.
14. What is the meaning of flotation speed and the speed of flotation?
A: Flotation speed refers to the flotation time required when a certain recovery rate (or flotation unit production capacity) is reached.
Increasing the recovery rate and shortening the flotation time, that is, increasing the flotation speed, so increasing the flotation speed is the main work that should be paid attention to and studied in the ore dressing production.
15. What are the measures to increase the speed of flotation?
Answer: 1. Reasonably adjust the prescription, especially pay attention to the amount of foaming agent. Generally speaking, slightly increasing the amount of foaming agent will increase the flotation speed, but the foaming agent will reduce the selectivity, so it is selected. In the case of a large collection dose, it should be noted that the amount of the foaming agent should not be excessive.
2. In the appropriate range, increase the impeller speed of the flotation machine, reduce the depth of the groove, and reduce the gap of the impeller cover to increase the amount of inflation.
3. Pass the slurry through the flotation tank as soon as possible.
4, the size of the selection tank must be appropriate, too large to make the slurry residence time is too long, not only the bubble depletion, but also reduce the flotation speed.
5. Control the proper slurry concentration to get the maximum flotation speed.
16. What is positive flotation? What is anti-flotation?
A: Positive flotation is to float useful minerals into the foam product and leave the gangue in the slurry; reverse flotation is to float the gangue into the foam product and leave the useful minerals in the slurry.
17. What is priority flotation? What is hybrid flotation?
A: If the ore contains two or more kinds of useful minerals, there are two kinds of flotation methods. One is to select the useful minerals one at a time into a single concentrate. This method is called priority floating. Alternatively, the useful minerals are selected together as a mixed concentrate, and then the useful minerals in the mixed concentrate are sorted one by one. This method is called mixed flotation.
18. What is the main effect or influence of water on flotation?
A: The main function of water is to form a slurry, which is convenient for minerals to float by means of bubbles under the action of chemicals. Its effect on flotation: 1, dissolution, the dissolution of various substances in water; 2, hydration minerals if hydrated, will reduce the floatability.
19. What operations are included in the flotation process, and what is the purpose?
Answer: 1. The slurry preparation operation before flotation (mainly grinding and grading operation) aims to obtain the coarse-grained, basically monomer-dissociated ore particles. The concentration of the slurry entering the flotation operation must be adapted to the flotation process. Claim.
2, dosing and pulping operation, the purpose is to adjust the physical and chemical properties of the interface with the control, to promote the selective attachment of bubbles and mineral particles, so as to achieve the purpose of separation, the type and quantity of additives should be determined according to the specific ore properties.
3. Inflatable flotation operation, the adjusted slurry enters the flotation machine, and a large amount of diffuse bubbles are formed due to the aeration stirring action of the flotation machine, which provides the opportunity for the ore particles to contact with the bubbles, and the floatable mineral particles are attached to On the bubble, a mineralized foam is formed, and the foam product is collected to obtain a flotation concentrate, and the poorly floatable ore remains in the slurry to form a tailings.
20, according to the use of different types of flotation drugs?
Answer: 1. Collecting agent: It acts on the surface of minerals. It adheres to the surface of minerals and can enhance the hydrophobicity of mineral surfaces, which is beneficial to the collection of mineral particles on bubbles.
2, foaming agent: foam is the medium for the floating of the mineral particles during flotation.
3. Inhibitor: It is an agent that reduces the floatability of minerals.
4. Activator: It is an agent that eliminates the inhibition and promotes the floatability, which makes the mineral surface easy to interact with the collector.
5, medium regulator: its main role is to adjust the pH value of the pulp, adjust the role of other agents, eliminate the harmful effects of flotation, and adjust the dispersion and agglomeration of the pulp.
21. What does PH mean? What is its scope and how is it divided?
A: PH value stands for pH and it ranges from 1 to 14. PH value 1-7 is acidic; 7-14 is alkaline.
22. What kind of medium conditioner should be added when the pulp contains harmful metal ions?
A: The pulp contains many metal ions harmful to flotation. Most of these ions are metal ions, such as iron, calcium, and copper ions. These ions are often used to form poorly soluble precipitates by using sodium sulfide, alkali, and soda. Eliminate the effects of harmful ions.
23. Where is the usual flotation agent applied? What is the order of dosing?
A: The choice of dosing location should be related to the action and dissolution rate of the drug.
The media conditioning agent is typically added to the ball mill to remove the deleterious effects of inevitable ionation on flotation by activation or inhibition.
The inhibitor should be added to the collector before it is usually added to the ball mill. The activator is often added to the mixing tank or flotation machine.
In order to promote the dissolution and dispersion of the insoluble collector, the time of growth and mineral action is also often added to the mill. The xanthate is generally added to the flotation machine, the slurry tank or the extreme overflow.
The usual dosing order is:
1. Flotation of raw ore: adjusting agent → inhibitor → collector → foaming agent
2. When floating minerals are suppressed: activator→collector→foaming agent
24, there are several commonly used dosing methods, why?
A: Flotation agents are often added in two ways: 1. One-time dosing; 2. Sub-dosing.
One-time dosing refers to adding a certain agent before flotation, which can increase the initial speed of the flotation process. Although the speed is slower in the later stage, the total flotation time is still short, which is beneficial to improve the flotation index.
Sub-dosing refers to adding a certain batch of drugs in several batches during the flotation process. Generally, 60-70% of the total amount is added before the flotation, and the remaining 30-40% is added to the appropriate place in several batches. Sub-dosing can improve the quality of concentrate, but the flotation time is longer. Generally, it is easy to be taken away by foam machinery, difficult to react in pulp, and some poorly selected or easily decomposed. The failed drug should be administered in stages.
25. How many methods are currently used to strengthen the effect of the drug?
A: The role of strengthening agents: can improve the flotation speed and improve the flotation index, and reduce the amount of rare chemicals.
At present, several methods are commonly used: 1. Mixed medication; 2. Correct control of other process factors; 3. Correct selection of dosing sites and dosing methods; 4. Proper storage of medicaments.
26. Why does mixed medication improve flotation?
Answer: The effect of mixed drugs is related to the non-uniformity of mineral surface and the interaction between various chemicals. The surface properties of minerals are not uniform, and the degree of oxidation is different. There may be different activation zones for different collectors. Therefore, the mixed drug may increase the coverage density of the mineral surface collector, thereby improving the flotation effect, and the co-adsorption by the interaction between the various collectors may also increase the ability of the drug to be collected, thereby increasing the floatation. Selected indicators.
27. How to increase the amount of aeration of the mechanical agitation flotation machine (into the amount of aeration in the slurry)?
Answer: 1. The speed of the impeller: the faster the impeller speed, the larger the air volume, the lower the impeller speed and the lower the air volume;
2. Reducing the depth of the flotation tank can also increase the aeration volume of the slurry;
3. The concentration of the slurry also has a great influence on the amount of aeration and the degree of dispersion. When the concentration of the pulp increases within a certain limit, the degree of inflation and dispersion also increases, but the concentration cannot be too large. If the concentration is too large, the amount of inflation will deteriorate.
28. What effect does the size of the bubble have on the flotation effect?
A: The size of the bubble has a certain effect on the effect of flotation. If the bubble is small, the better the air dispersion is, which increases the surface area of ​​the bubble and the chance of contact with the ore. It is beneficial to the flotation and can improve the flotation index. However, if the bubble is too small, the lifting speed is small. This is harmful, so the bubbles should not be too large during flotation. It is better to be small, but not too small.
29, the role of water quality in the flotation? What is hard water? How to soften?
A: water or flotation agent may affect the presence of mineral role in mineral ore soluble salts cause activation or inhibition, usually a carbonate, sulfate, phosphate, calcium, magnesium, and sodium compounds Silicon compounds, which contain a large amount of calcium salt in water, become hard water. In hard water, when valeric acid and soap are used for flotation, a large amount of chemicals are consumed. When water is in contact with metal minerals, water will contain some metal ions, such as Iron, copper, zinc, etc. If the contact is sulfide ore, these metals will form sulfate in the water, which becomes a refractory mineral. In addition, the oxygen dissolved in the water also has a great influence on the flotation. Due to the adsorption of oxygen on the mineral surface, the mineral is strengthened. Hydrophobicity promotes the action of certain collectors and minerals, which accelerates flotation and improves the index. However, when the flotation water contains a large amount of organic matter, it consumes oxygen dissolved in water, thus reducing the sulfide ore. The flotation speed severely undermines the flotation process.
Hard water softening mainly has the following methods:
1. The hardness of carbonate can be eliminated by adding lime;
2, calcium non-carbonate hardness can be added with soda elimination;
3, magnesium non-carbonate hardness plus soda with the same fashion needs to add lime or caustic to eliminate.
30. There are several types of flotation machines. Which one is commonly used?
A: According to the way of inflation and agitation, it can be divided into the following three types:
1. A mechanical agitation flotation machine which inflates and agitates the slurry by rotation of the impeller or the return rotor;
2, a gas-pressing flotation machine, the flotation machine is externally blown into the compressed air to complete the aeration and agitation of the slurry;
3. Hybrid flotation machine: In addition to the rotation or agitation of the slurry inlet by the rotation of the impeller or the return rotor, the flotation machine also sends compressed air from the external blower.
A mechanically agitated flotation machine is commonly used.
31. Structural characteristics and working characteristics of mechanical stirring flotation machine?
Answer: 1. The cover plate is equipped with 18-20 guide vanes, which have guiding effect on the slurry which the impeller pulls out;
2. The size of the gap between the impeller and the guide vane of the cover plate has a great influence on the inspiratory capacity and power consumption of the flotation machine;
3. In the lower part of the air, there is a circulation hole that regulates the circulation volume of the slurry, and the circulation amount is controlled by the gate. Therefore, the amount of slurry in the center of the impeller can be adjusted according to the change of the external ore supply.
32. What are the characteristics of the hybrid flotation machine compared with other flotation machines?
Answer: 1. The amount of inflation is easy to adjust separately; 2. The mechanical agitator wears less; 3. The selection index is better; 4. The power consumption is low.
33. What is the impact of the gap between the impeller and the cover plate on the flotation? How much should our factory control?
A: Generally speaking, the smaller the gap, the greater the energy consumption, and the amount of inflation will increase accordingly; the gap will increase, the energy consumption will decrease, but the amount of inflation will also decrease, in order to control the appropriate amount of inflation, reduce Energy consumption, improve the flotation effect, the gap is generally controlled between 5-8mm, the gap of the impeller cover of our factory is 8mm.
34, the role of the cover?
Answer: 1. When the slurry is pulled out by the impeller, a vacuum is formed under the cover plate;
2. Adjust the amount of pulp entering the impeller;
3. The amount of pulp entering the impeller when parking;
4, a certain degree of steady flow.
35. What are the effects of slime on flotation and how can it be improved?
A: It has an impact. 1. Easy to accumulate in the foam, affecting the quality of the concentrate;
2, the cover on the surface of the coarse grain, affecting the coarse grain floating, affecting the recovery rate;
3, adsorption of a large number of agents, increase drug consumption;
4. Increase the viscosity of the slurry and make the aeration condition of the flotation machine worse.
Improvements:
1. Adding a slime dispersant to disperse the slime;
2. Adding medicine in batches and batches to avoid absorption by the slime once;
3, the use of relatively thin pulp, to avoid the inclusion of mineral mud in the air bubbles, but also reduce the viscosity of the pulp;
4, mud removal.
36. What are the flotation schemes for polymetallic sulphide ore?
Answer: 1. Priority flotation; 2. Mixed flotation; 3. Partial hybrid flotation; 4. Pressable floating flotation.
37. What is the relationship between the choice of flotation process and the nature of the ore?
A: The choice of flotation process is related to the nature of the ore and the requirements of the concentrate. Among them, the nature of the ore is very important. When selecting, consider: 1. The disseminated particles and common characteristics of useful minerals in the ore. 2. The ore is in the grinding. Mudification, 3, mineral floatability, 4, mineral composition and soluble salt content, 5, the original ore variety, 6, the degree of oxidation of the ore.
38. How to determine whether a certain item uses a one- or two-stage flotation process?
A: The flotation process can be one-stage, two-stage, or multi-stage. The number of stages in the flotation process is mainly related to the characteristics of the useful minerals in the ore and the mud-forming process of the ore in the grinding.
A grinding process is to directly grind the ore to the required particle size and then carry out flotation to obtain the final product without re-grinding any of the products. Generally, the ore that is uniformly impregnated with useful minerals is subjected to a flotation process.
The second stage flotation process is also called the stage flotation process. The main purpose of the stage flotation process is to avoid the crushing and muddy of useful minerals and gangues, so that the gangue is only discharged at the coarser grain size, sometimes In order to select a coarse concentrate which is also partially dissociated, it is generally treated with a mineral-disseminated ore, and a stage flotation process is employed.
39. How to select the flotation process and how many times to select the number of sweeps?
A: After determining the ore flotation principle process, it is also necessary to solve the internal structure of the process, that is, to determine the number of selections and sweeps in the process. Their determination depends on the grade of the ore, the floatability of the useful minerals, and the precision. The quality of the mine is determined by the requirements.
When the ore grade is low, the floatability of the useful mineral is good, and the quality of the concentrate is high, the selection should be strengthened, that is, the selection time is lengthened, and the number of selections is increased.
When the ore grade is high, the floatability of the useful mineral is poor, and the quality of the concentrate is not high, the sweeping should be strengthened, that is, the sweeping time is lengthened, and the number of sweeps is increased.
40. What are the new developments in China's flotation equipment?
A: In recent years, China has carried out a lot of research and development on the diversification and large-scale flotation machines and the improvement of existing flotation machines. The research and use are described as follows:
1. Rod-shaped flotation machine: It is characterized in that there is a suction wheel in the bag in the suction slot, and the solution is self-suction and returning from the mine. The impeller has a simple structure and convenient maintenance.
2, annular flotation: This is a newly developed flotation machine in China, in addition to the use of the impeller to produce the negative pressure caused by the slurry, which uses the double-shaped slurry flow from the bottom to draw air from the center of the impeller, with two The secondary suction effect has a larger aeration area and improves the efficiency. The machine has a simple structure and is suitable for coarse flotation;

41. What is the basis for selecting flotation equipment?
Answer: The selection and determination of the type and specification of flotation equipment are related to raw ore properties (ore density, particle size, mud content, grade, floatability, etc.), equipment performance, plant size, process structure, and series division.
42. How to choose the flotation machine model?
A: The nature of the mine and the flotation operation requirements, ore of different density and particle size must use different characteristics of the flotation machine. For example, ore with a large particle size or high density, a high-energy mechanical agitation flotation machine should be used. In the low-grade vulcanization flotation process, the low-speed inflation is more favorable for the sorting effect, and it is not suitable to use a high-inflating flotation machine. For ore that is prone to viscous foam during flotation, a flotation machine with a large amount of aeration should be used. The selected operations are mainly to improve the concentrate grade, and the flotation foam should be thinner. Therefore, there is no need for a larger aerated flotation machine. Therefore, the flotation unit of the general selection operation is different from the roughing operation flotation unit. .
43. How to determine the specifications and quantity of the flotation machine?
Answer: According to the reasonable selection of the specifications of the flotation machine according to the slurry flow rate, in order to ensure the selection effect, it is necessary to ensure that the slurry in each flotation tank has a certain residence time. Therefore, the specifications of the flotation machine are adapted to the scale of the selection plant. Reduce the number of flotation machines, try to play the role of large flotation machine, for easy selection of ore, you can use a single series.
After determining the specifications, determine the number of flotation machines by conducting technical and economic comparisons. Generally, comprehensive comparison should be made in the selection of indicators, operating expenses, operation management, maintenance and overhaul to ensure proper flotation time to ensure the selection of indicators.
44. How to determine the flotation time during design?
Answer: The length of the flotation time directly affects the volume of the flotation machine and the selection index. It is determined that the flotation time of the production is generally based on the flotation time determined by the ore dressing test result and then multiplied by an adjustment factor of 1.5.
