Low grade ores – Smelt, leach or concentrate?
About 80% of the world's copper comes from copper sulphide and copper–iron sulphide ores, with chalcopyrite (CuFeS 2) being the most common mineral in these ores. Cu–Fe–S minerals are not easily dissolved by aqueous solutions, so the vast majority of copper extraction from these minerals is pyrometallurgical.
