Jun 29, 2018 In the extraction of copper from its Sulphide Ore, when ore is subjected to roasting some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S to give copper metal. In this process, Cu 2 S behaves as reducing agent 2Cu 2 S+3O 2 +heat→2Cu 2 O(s)+2SO 2 (g). 2Cu 2 O+Cu 2 S+heat→ 6Cu(s)+SO 2 (g). In electrolytic refining of copper, the impurities left behind at anode.

Apr 17, 2020 To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash. This mixture is placed into a digester, where it is heated under steam pressure. Caustic soda is added, which dissolves the alumina from the ore. The other impurities are left as solids. After this, a filter separates the solids from the solution.

Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2.

The ore is ground to 20 mesh and is leached with strong hot nitric acid in acid proof earthenware pots. The amount of acid used is 121 pounds of 100 per cent nitric acid to 500 pounds of ore, the acid being diluted to 38 per cent strength. However, the strength may be varied somewhat, ores high in sulphates requiring stronger acid.
