Its purpose is to separate the metals so that they can be transformed into a watersoluble form for further hydrometallurgical processing. The smelting of sulphidic ores produces a partially oxidized metal concentrate (matte). In smelting, the worthless material, usually iron, forms a slag with fluxing material and is converted into the oxide.
