FIELD: various technological processes.
SUBSTANCE: invention relates to reduction-sulphiding melting of oxidised nickel ores on matte in ore-smelting furnaces. Mixture contains oxidised nickel ore, a sulphidizer, a reducing agent and a flux. As a sulphidizer, it contains sulphide copper ore cinder, and as a reducing agent – coke, with the following ratio of ingredients, wt.%: coke – 2.6; sulphidizer – 34.2; flux – 10.5; oxidised nickel ore – balance.
EFFECT: higher content of non-ferrous metals in matte and their extraction into matte.
