Steps Of Extraction Of Copper From Chalcopyrite

Aug 21 2020018332the copper ii ions in the chalcopyrite are reduced to copper i sulfide which is reduced further to copper metal in the final stage the iron in the chalcopyrite ends up converted into an iron ii silicate slag which is removed most of the sulfur in the chalcopyrite.
