The method that would be used to extract copper from these ores is called roasting. Roasting involves the ore being roasted in a furnace with oxygen and during the process; the metal is converted into a copper oxide and then later, the oxide is removed. b)Write a balanced chemical equation for the process used to extract copper from these ores.

Copper Mining and Production Processes Explained

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Jetti Resources' quest for copper mining's holy grail ...

Answer: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 to give copper metal. In this process, Cu2S behaves as reducing agent. 2Cu2S+3O2+heat→2Cu2O(s)+2SO2(g) 2Cu2O+Cu2S+heat→ 6Cu(s)+SO2(g) In electrolytic refining of copper, the ...
