Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.

Mar 10, 2021 The copper ore beneficiation process generally adopts a relatively simple process. After one stage grinding, the fineness -200 mesh accounts for about 50% to 70%, 1 roughing, 2 to 3 selections, and 1 to 2 sweeping. If the copper mineral impregnation particle size is relatively fine, the stage grinding process can be considered.

In addition, Fig. 6 (B) shows that the addition of silver sulfide powder greatly enhanced copper dissolution from enargite, likely due to silver ions from silver sulfide enhancing enargite dissolution. The suppression of enargite dissolution at high silver ion concentrations may be caused by silver sulfide precipitation on the enargite surface.
