Role of silica in extraction of copper from copper pyrites

The copper ores are mostly found in the north of India The extraction of copper also involves many steps The ore used for extraction is copper pyrites, which is crushed, concentrated and then heated in the presence of air During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulfide and cuprous sulfide
