ABSTRACT OF THE DISCLOSURE 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. A certain particle size is maintained. Sulfide ores are supplied to a melting burner, which directs a flame jet into the fluidized bed of coal.
