In the smelting process of recovering metal from non ferrous metal oxide ores or concentrates and/or from fine grained non ferrous metal sulfide ores or concentrates particularly from non ferrous heavy metal sulfide ores or concentrates any sulfide ores are initially oxidized The ores or concentrates are then supplied to a fluidized bed of coal in a melting gasifier 1 A certain particle

The process of smelting is much more than just melting the metal out of its ore Most of the ores are the chemical compounds of metals and other elements such as oxygen where the ore is present as an oxide sulphur where the ore is present in the form of sulphide or carbon and oxygen together results in the formation of carbonate
