How copper is made material used processing steps

The current trends in copper processing are towards methods and equipment that use less energy and produce less air pollution and solid waste In the United States this is a difficult assignment because of the stringent environmental controls and the very low concentration copper ores that are available In some cases the production costs may

Copper Production How Is Copper Made

Copper processing Roasting Smelting Converting Once a concentrate has been produced containing copper and other metals of value such as gold and silver the next step is to remove impurity elements In older processes the concentrate containing between 5 and 10 percent water is first roasted in a cylindrical refractory lined furnace of either the hearth or fluidized

Current Status of Copper Ore Processing A Review

IN PROCESSING COPPER ORES In recent times a low copper content in ores has been observed ores containing % copper are used for processing in Canada and the United States and ores containing at least % copper are used in Russia [4] owing to the exhaustion of rich copper resources The flowsheet of processing copper ores is

Progress in the treatment of copper II containing

Acidic mine water AMW produced during polymetallic sulfide processing contains valuable metals such as copper and zinc Chemical precipitation is widely used to treat AMW and lime is often added to produce metal precipitation; this step requires a large amount of precipitant that cannot be recycled and produces a large amount of sludge [ 109 ]
