Extraction Of Copper Mining, Concentration, Smelting

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

NCERT Solutions for Class 12 Chemistry Chapter 6 General

Why is the extraction of copper from pyrites more difficult than that from its oxide ore through reduction? Solution: Hydrogen sulphide and carbon disulphide (CS 2) has a larger ∆ f G (Gibbs free energy of formation) than copper (I) sulphide. Thus, C and H 2 S will not be able to reduce Cu 2 S to Cu. Whereas, ∆ f G of Cu 2O is larger than carbon monoxide’s, thus C can reduce copper
