In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu2O which reacts with the remaining Cu2S sulphide ore to give copper metal.Cu2S 2Cu2O 6Cu SO2 In this process, Cu2S behaves as reducing agent.
Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copperII oxide and copperII sulfide. CopperII oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1 copper but they are still used because copper is so valuable.
Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.
Copper mines are only set up where there is more than 5 kg of copper per tonne of rock 0.5 by mass. Ideally, the figure should be closer to 2. The worlds largest copper ore deposits are found in Chile on the west coast of South America.
