Sand gold content gold ore is very low, and there are variety of forms in which a sheet of gold mostly, due to the special shape of the sheet metal, the sheet metal fine particle can float above the water, so the use of conventional reselection The method and the re-election equipment are difficult to achieve a good treatment effect, and the recovery rate is difficult to be guaranteed.
The ore dressing method of the gold deposit is mainly the re-election method. The re-election of the gold-gold mine basically uses water as the medium for mineral processing. Therefore, for the recovery of the flake gold which can float on the water surface, the ordinary re-election equipment is difficult to exert the application effect. In order to improve the recovery rate of flake gold, based on the original sawtooth wave jig, it has been improved and innovated, and a new type of sawtooth jig has been successfully developed. This machine adopts a cam different from the ordinary sawtooth jig. The structure enhances the inhalation of the heavy minerals in the vertical alternating water flow during the descending process, so that the flaky gold floating on the water surface can be settled and effectively recovered, and at the same time, the content of impurities in the gold concentrate can be reduced. The recovery of flake gold is no longer a problem. According to the results of the practical data, the recovery rate of the gold to the ultrafine flake gold is more than 75%, and the recovery rate of the coarser flake gold is 85%. The above height greatly reduces the gold loss rate and ensures the mineral processing and economic indicators of gold ore beneficiation.
