Question

A mixture of Cu2S and FeS called matte is produced in one of the metallurgical operations in the extraction of copper. The name of this process is :

A: Smelting
B: Roasting
C: Bessemarization
D: Electro refining

Answer 1

Answer:

Smelting is the name of that process

Answer 2

A mixture of Cu2S and FeS called matte is produced in one of the metallurgical operations in the extraction of copper. The name of this process is C: Bessemarization.

• Bessemarization is used to obtain pure copper in Bessemer converters and this pure copper is also known as blister copper.
• Smelting is used to extract metal such as iron from its ore. in this technique carbon, coke and flux are introduced in a large container at a high temperature.
• In roasting, sulphide ore at high temperatures above their melting point is heated to reduce sulphide ores to oxides.
• In electrolytic refining anode and cathode is used in a set-up to purify metals such as Ag, Cu and Pb.
