Copper Production: How Is Copper Made? - .

26.09.2019 · Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

Copper Scrap - an overview | ScienceDirect Topics

The main smelting product is molten black copper (80% Cu), which is converted to rough copper (96% Cu) then fire refined and cast into anodes (98.5% Cu). These processes do not completely remove Ni and Sn from Cu, so the refining furnace product must be electrorefined. Electrorefining also recovers Ag, Au, and platinum-group metals. Secondary copper electro refining is similar to primary ...
