copper nickel sulphide matte separation technique

Copper extraction Wikipedia

All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting.Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.. Carbonate concentrates are a relatively minor product
