bessemerisation of copper

Define bessemerisation? - Chemistry QA

2021-11-20  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, that ...

METALLURGY OF COPPER-EXTRACTION OF COPPER

2012-7-24  Copper metal is extracted from molten matte through bessemerization . The matte is introduced in to Bessemer converter which uphold by tuyers. The air is blown through the molten matte. Blast of air converts Cu2S partly into Cu2O which reacts with remaining Cu2S to give molten copper. 2Cu2S + 3O2 è 2Cu2O + 2SO2.

[SOLVED] The final step for the extraction of copper ...

The sulphide ore of copper is heated in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide. Self-reduction of CuS to Cu can be carried out in either Bessemer converter or Pierce-Smith converter. 2 C u 2 S + 3 O − 2 → 2 C u 2 O + 2 S O 2 2 C u 2 O + C u 2 S ...
