Copper Flotation
Remember that only % of the ore is copper. 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 groundup limestone) to give a basic pH, pine oil (yes, it comes from trees a byproduct of paper mills) to make bubbles, an alcohol to strengthen the .
A study of the flotation characteristics of a complex ...
Tailings mineralogy of LQ ore after sulphidisation showed a copper deportment of % cuprite, % malachite, % chalcopyrite and % chrysocolla, suggesting that all oxide copper minerals present in the LQ ore, except chrysocolla, are amenable to flotation using SIBX after sulphidisation. This observation was further verified through sulphidisation in a microflotation .
