Copper Recovery Through Smelter Slag Flotation in …

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 ...

Improving the performance of a low-grade porphyry copper ore flotation

A large porphyry copper flotation plant has been simulated using a flotation model developed from first principles using the hydrophobic force as a kinetic parameter (Huang et al., 2022, Gupta et al., 2022).The input to the simulation was the size-by-class liberation matrix (m ij) of a flotation feed, which was essential for predicting the …
