Define bessemerisation? - Chemistry QA

2020-12-7  Answer: Bessemerisation is a method in which the air is blown into the molten copper mat that is deposited in a Bessemer converter. In the final stage of smelting, the other products that remain, including FeS, are oxidized and removed as slag (FeSiO 3 ). Cu 2 S (Copper sulfide) is partially converted into Cu 2 O (copper oxide) by the air blast ...
