FIELD: metallurgy.
SUBSTANCE: procedure for extraction of gold from rejects of electronic scrap consists in melting in furnace with usage of melted collector wherein gold is concentrated. As collector there is used melted metal bismuth with addition of 2 wt % of germanium. Collector is mixed with rejects of electronic scrap at ratio (1.5-2):1 by weight at temperature 600°C, and conditioned for 10-30 minutes, further, temperature in the furnace is raised to 900-1000°C. Produced melt of alloy bismuth-gold is oxidised with transition of bismuth into oxide and gold - to globule refined with gold.
EFFECT: simplification and reduced cost of procedure for extraction of gold from rejects of electronic scrap.
