RECOVERY OF COPPER FROM OXIDE COPPER ORE BY

Copper is the name of a metallic element with an atomic number of 29. The name ‘Copper’ comes from ‘Cyprium’ which means the metal of Cyprus where the mining of the copper began. Copper is being mined for thousands of years and it is a vital metal of mankind with very high electrical and thermal conductivity. Copper hasCopper and Cyanide Recovery in Cyanidation Effluents,smelting. This is a common practice in William Mining Co., which produces a copper sulfate acidic solution that goes to the zinc and arsenopyrite froth flotation circuit or to an iron cementation process before disposal.
