60 Centuries of Copper: The Flotation Process

The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain...

Copper Sulfide Flotation - Mineral Processing & Metallurgy

The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite , arsenopyrite, and calcite with 3 to 4% copper.

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,...

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Copper Mining and Processing: Processing of Copper Ores ...

After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.

Segregation | Article about Segregation by The Free Dictionary

in nonferrous metallurgy, the combined process of roasting an oxide ore and subsequent concentration. The aim of segregation is the conversion of valuable metals in difficult-to-concentrate ores into metallic granules 20–40 microns in size. The metals are then removed in the concentrate by flotation methods or magnetic separation.
