Extraction of copper from copper pyrites (CuFeS2

Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S + O 2-----> SO 2 4AS + 3O 2----->2AS 2 O 3 2.

Rcovery of gold in pyritic ores Mine Engineer.Com

One USBM paper summed up five noticeable characteristics of auriferous pyritic ores. The gold occurs as tiny flakes on the crystallographic planes of the pyrite. The gold flakes are very small in size, 5-10 microns. The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite).
