- Chalcopyrite Tin Mining Plant Impact S
It is commonly understood that elemental sulfur forms a passive layer on the chalcopyrite surface, preventing it from leaching. The silver cation (Ag +) induces the semiconducting property of the passive layer by generating Ag 2 S species or defects sites. In the present work, the influence of Ag + cation on the elemental sulfur passive layer is …

What is Chalcopyrite? Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS 2.It occurs in most sulfide mineral deposits throughout the world and has been the most important ore of copper for thousands of years..

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
