Extraction of copper stages
(1)concentration of ore Most copper ores contain only a small percentage of copper metal bound up within valuableoreminerals, with the remainder of the ore being unwanted rock organgueminerals, typicallysilicate mineralsor oxide minerals for which there is often no valueThe first stage of any process within a metallurgical treatment circuit is accurate grinding orcomminution, where the rock is crushed to produce small particles (<100 μm) consisting of individual mineral phases
(2)Froth floatation process removal of primary sulfide ore
(3) Roasting:
The roasting process is generally undertaken in combination withreverberatory furnaces. In the roaster, the copper concentrate is partially oxidised to produce "calcine" andsulfur dioxidegas. Thestoichiometryof the reaction which occurs is: 2 CuFeS2+ 3 O2→ 2 FeO + 2 CuS + 2 SO2
