How is copper extracted from its ore explain the process with relevant equations? 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.

Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore through reduction. How is blister copper formed? The liquid matte is oxidised with air to form blister copper in a converter. ... The blister copper produced by this process is 99% pure copper. The name 'blister' copper comes from the fact that this final ...

Answer. Copper is extracted from copper pyrites. After roasting, the ore is mixed with silica and coke and then smelted into a blast furnace. The matte obtained from the blast furnace is charged into a silica lined converter. Some silica is also added and a hot air blast is thrown into the mixture to obtain blister copper which is purified by ...
