Why does copper obtained in the extraction from copper pyrites? Why does copper obtained in the extraction from copper pyrites have a blistered appearance?

Why does copper obtained in the extraction from copper pyrites have a blister appearance? (b) Copper is extracted from its principal ore copper pyrites (CuFeS2). … The sulphur dioxide escaping from the melt gets trapped in the cooler parts of the surface giving a blistery appearance for copper and hence it is called blister copper.
Why is copper extracted by pyrite? – Copper pyrites is the ore of copper in which copper is present in the form of its sulphide. So, this gives a roasting reaction to give copper oxide as a main product. But alongside this, the ore also contains iron. So, we add some amount of silica in order to remove iron as slag.
What are the important ore of copper How is copper extracted from copper pyrites? After roasting, the ore is mixed with silica and coke and then smelted in a blast furnace. The matte obtained from the blast furnace is charged into a silica lined converter.
