Copper Flotation - Elmhurst College
The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of stone mills) to make bubbles, an alcohol to strengthen the bubbles, and a ...
