  • Copper Smelting Slag Recovery- Metalcess

    Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper. The rest are iron minerals like magnetic iron ore, metallic iron and gangue like fayalite, hedenbergite and amorphous phase matter. Such slag can be concentrated by separation and enrichment to obtain copper concentrate.
