Comparing lead and copper activation on pyrite with ...

Copper ions are often added in the flotation of gold-bearing pyrite to activate pyrite so that high gold and pyrite recoveries can be achieved. However, the residual copper ions are problematic in subsequent cyanidation by consuming cyanide. There is a great need to replace copper ions by lead ions which are beneficial to cyanidation. This study compared lead and copper activation on pyrite ...
