Egyptian Copper Processing MATSE 081 Materials In Today Copper Production How Is Copper Made The Balance

Egyptian Copper Processing Print Native copper occurs in a very limited supply so the start of the Copper Age is marked by the discovery of smelting copper from its ores which allows for a ready supply of copperCopper is typically extracted from oxide and sulfide ores that contain between 05 and 20 percent copper The refining techniques employed by copper producers depend on the ore type as well as other economic and environmental factors Currently about 80 percent of global copper production is

Azurite The blue gem material ore of copper and pigmentMETALLURGY OF COPPER EXTRACTION OF COPPER BLISTER

Geologists know that abundant azurite is often found in the rocks above deposits of copper ore That enables them to use azurite as an indicator mineral in the search for subsurface copper deposits The presence of abundant azurite indicates the possibility of finding some form of copper ore below nearby or up a contemporary or ancient hydraulic gradientIt contains impurities mainly iron but little amount of As Zn Pb Ag and Au may also be present These impurities adversely affect the electrical as well as mechanical properties of copper Therefore they must be removed
