Copper Flotation

Copper Flotation

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 paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a,Froth Flotation Process - Mineral Processing & Metallurgy,Copper Flotation - Mineral Processing & MetallurgyCopper Flotation - Mineral Processing & Metallurgy,Mar 19, 2017· Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter., as a slight excess may cause an undue amount of froth to form,60 Centuries of Copper: The Flotation Process,In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks.
