Smelting an overview ScienceDirect Topics

Smelting maximizes the separation of ore from gangue minerals. The concentrates undergo smelting and converting in a furnace at a high temperature to produce a silicate melt (slag) and an immiscible melt (matte) due to density differences. The flux (limestone) is added to the furnace to reduce the melting temperature in the matte.
