Abstract
A process for reduction smelting of copper-, nickel- or cobalt-containing materials in which such a material, at least partly in oxidic form is heated or combusted in finely divided form in a neutral or oxidizing flame to provide superheated particles. The superheated particles are then distributed onto a thin layer of coke. The materials in the particles are reduced in the thin layer of coke to metals or mattes or, in the case of iron, to wustite which forms a discardable slag with flux. Reduced product and slag form separate molten layers underneath the thin coke layer. All heat necessary for reduction and melting of product and slag is provided directly by the flame both in sensible heat in the superheated particles and by radiation.
