Smelting Then, copper concentrates are mixed with silica (sand) and limestone and heated in a furnace to form two naturally-separating layers. One layer is a waste containing iron and silica compounds and is discarded as slag slag Byproduct left after a desired metal is thermally separated from its raw ore. .

Author Blast FurnaceThe production of copper in the flash smelting process is accompanied with a large amount of copper-rich slag, which has to be treated with the aim of copper recovery. Copper flash smelting consists of blowing fine, dried copper sulphide concentrate and silica flux with air, oxygen-enriched air or oxygen blast into a hot (≈1500K) hearth-type furnace, (see Figure 1).

Flotation concentrates undergo smelting and converting in a furnace at a temperature exceeding 1300C to produce a silicate melt (slag) and an immiscible sulfide melt (matte) due to density differences. Limestone is added to the furnace to reduce the melting temperature of the platinum and base-metal sulfides accumulated in the matte (green matte).
