Advantages of extraction oc copper

copper mining and extraction sulfide orpper can be extracted from its ore by underground sinking a vertical shaft into the earth to an appropriate depth and driving horizontal tunnels into the ore. open pit 90% of ore is mined by this method. ores near the surface can be quarried after removal of the surface layers.how copper is made material, used, processing, stepsthe first mention of the systematic extraction of copper ore comes from about 3800 b.c. when an egyptian reference describes mining operations on the sinai peninsula. in about 3 b.c. , large deposits of copper ore were found on the island of cyprus in the mediterranean sea.extraction of copperextraction of copper from sulphide ore large amount of copper are obtained from copper pyrite (cufes2) by smelting. ores containing 4% or more copper are treated by smelting process. very poor ores are treated by hydrometallurgical process. extraction of copper by smelting process following steps are involved in the extraction of copper.copper extraction overviewhistoryconcentrationfroth flotationhydrometallurgical extractionsulfide smeltingconcentrate and copper marketingsee also
