Extraction Of Copper Ore

Copper Mining And Extraction Oxide Ores

Copper mining and extraction oxide ores copper is refined from ores in the ground either through underground or openpit mines most of the copper ores mined today are oxide or sulfide ores

Copper Processing Ores Britannica

The extraction of copper from ore is normally carried out in three major steps the first step mineral processing is to liberate the copper minerals and remove waste constituentssuch as alumina limestone pyrite and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper

Innovations Introduction Tocopper Mining Extraction

By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals such ores originate from sulfurbearing volcanic magmas which have separated into metal sulfides and siliceous melts the copper has concentrated almost entirely into the sulfide fraction and if this becomes separated from the siliceous melt it can become deposited in veins or in fissures in the
