copper slag flotation plant

Enhancing the flotation recovery of copper minerals in ...

2020-1-1  Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue ...
