METHOD OF EXTRACTING PALLADIUM FROM WASTES OF ELECTRON RAW MATERIAL

摘要

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 850-1000C 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.
