FIELD: metallurgy.
SUBSTANCE: method consists in crumbling wastes, in their charging into furnace with collector and in melting. Also powder of metallic bismuth mixed with powder of electron raw material wastes at ratio 2:1 by weight is used as collector. Upon mixture charge, temperature in the furnace is raised to 850-1000°C and inert gas is blasted; further there is supplied air and simultaneously supply of inert gas is stopped for oxidising metallic bismuth and for separation of regulus containing extracted palladium, which is directed to refining.
EFFECT: simplification and reduction in price of method of palladium extraction from wastes of electron raw material.
