Flotation is widely used to treat a variety of vein gold ore.
In most cases, the flotation process is used to treat highly volatile sulphide gold-bearing ores with the most significant effect. Because the flotation method can not only maximize the gold enrichment into the sulfide concentrate, but also can obtain the waste tailings, and the ore dressing cost is also relatively low. Flotation is also used to treat multi-metal ores, such as gold - copper, gold - lead, gold - antimony, gold - copper - zinc - lead ores. For this kind of ore, the flotation process can effectively sort out various gold-bearing sulfide concentrates, which is conducive to the comprehensive utilization of mineral resources. In addition, so-called "difficult to dissolve" ores that cannot be directly treated by amalgamation or cyanidation are also required to be treated by a combined process including flotation.
Of course, the flotation method also has limitations. For coarse-grained ores, when the gold particles are larger than 0.2 mm, when the flotation gold industry is larger than 0.2 mm, the flotation method is difficult to handle; for ores that are difficult to obtain the necessary flotation conditions, such as sulfide-free Quartz gold ore is difficult to obtain stable flotation foam after pulping. It is difficult to use flotation method. In terms of economic indicators, the flotation method has a higher beneficiation cost than the re-election method and the amalgamation method because flotation requires a large amount of flotation reagents.
