FIELD: metallurgy.
SUBSTANCE: according to method, low-autogenous raw material processing in flash smelting furnace comprises supplying a metal-containing charge and flux as charge-gas flame to reaction zone of the said furnace by stream of oxygen or air enriched with oxygen, charge melting occurs to form a molten matte and slag, their separation by settling, separate liquid melting products and gases outputing. Charge composition comprises carbon containing reducer with fineness of 3-15 mm in an amount of 0.4 to 5 tons per hour in at volume ratio of 1:30 to 1:2 relative to flux.
EFFECT: increased productivity of flash smelting process, reduced probability of scull formation in uptake and slag bath of furnace, and also reduced losses of non-ferrous metals with waste slag.
