FIELD: metallurgy.
SUBSTANCE: method involves drying of concentrate and melting in the oven. At that, melting is performed in cylindrical reaction chamber of the oven at bubbling and rotation of the molten metal with oxygen-containing jets in sulphur to oxygen ratio 1:(1-1.1). After melting is completed, the molten metal is separated into slag and matte in collector.
EFFECT: continuous high efficiency method of processing of copper-nickel sulphide concentrates so that high-grade mattes are obtained and content of cobalt in slag is decreased.
