Nickel smelting and converting Ausmelt TSL Furnaces have been designed, built and operated to handle nickel concentrates with nickel content as low as 5%. Nickel converting is also available to upgrade low grade mattes before refining. PGM recovery can be targeted specifically using the Ausmelt TSL Process. Similarly,

The primary function of flash smelting is upgrading sulphide concentrate through oxidation then removal of impurities (primarily FeO, SO 2 and MgO) by separation of the slag and gas phases from the enriched sulphide stream (nickel matte) at temperatures in excess of 1300 °C. Flux must be added to allow the formation of a …
