FIELD: metallurgy.
SUBSTANCE: proposed method comprises preparation of charge by mixing the tinstone concentrate with coal and fluxing additives consisting of sodium carbonate and sodium chloride and reduction melting of said charge at 870°C. Then, obtained melt is cooled to separate metal from slag. Note here that charge melt is irradiated by nanosecond electromagnetic pulses for 10-30 minutes.
EFFECT: higher yield of lead, accelerated melting.
