Extraction of Copper and Zinc Chemistry, Class 12

May 15, 2020 (ii) copper sulphide is partially oxidised to cuprous oxide which further reacts with remaining copper sulphide to form copper and sulphur dioxide. 2 Cu 2 S + 3O 2 → 2Cu 2 O + 2SO 2. Cu 2 S + 2Cu 2 O —-> 6 Cu + SO 2. After the reaction has been completed, the converter is tilted and the molten copper is poured into sand moulds.

Copper Wikipedia

The cuprous oxide is converted to blister copper upon heating: 2 Cu 2 O → 4 Cu + O 2. The Sudbury matte process converted only half the sulfide to oxide and then used this oxide to remove the rest of the sulfur as oxide. It was then electrolytically refined and the anode mud exploited for the platinum and gold it contained. This step exploits

What are some ways to extract copper from copper oxide?

Extraction and purification of copper. Copper is less reactive than carbon, so it can be extracted from its ores by heating it with carbon. For example, copper is formed if copper oxide is heated strongly with charcoal which is mostly carbon: copper oxide + carbon → copper + carbon dioxide.
