[Solved] The ore copper pyrite is concentrated by

Copper is extracted from its principal ore Copper pyrites (CuFeS2). The ore is concentrated by froth flotation process. Then, the concentrated ore is roasted in a furnace where reactions remove sulphur and Arsenic gases: S+O2 →SO2 and 4As+3O2 2As2 O3 . The copper pyrite gets converted to a mixture of Cu 2 S and FeS by the reactions given below:

The most effective method of isolating the Cu minerals is froth flotation. This process causes the Cu minerals to become selectively attached to air bubbles rising through a slurry of finely ground ore in water (Fig. 1.4).Selectivity of flotation is created by using reagents, which make Cu minerals water repellent while leaving waste minerals wetted.
