A method for recycling metal bismuth from anode slime includes the following steps that a, sintering is performed; b, copper separation is performed so that a sulfate solution and copper separation slag can be obtained; c, gold separation is performed so that gold separation mother liquor can be obtained, wherein the concentration of sulfuric acid is 100 g / L to 120 g / L, the concentration of hydrochloric acid is 10 g / L to 15 g / L, the concentration of chloride ions is 25 g / L to 35 g / L, temperature is raised to 75 DEG C to 85 DEG C, excessive sodium chlorate is added, after a reaction, gold metal, platinum metal, palladium metal, tellurium metal and bismuth metal are dissolved in the gold separation mother liquor, then sodium sulfite is added in the gold separation mother liquor to separate gold so that gold separation liquid can be obtained; d, sodium chloride and sodium sulfite are added in the gold separation liquid obtained in the step c, the concentration of sodium chloride is controlled to be 250 g / L to 300 g / L, liquid temperature is controlled to be 75 DEG C to 85 DEG C, precious metal, tellurium and selenium in the liquid are reduced into suspended matter, and after filtration, bismuth separation liquid is obtained; and e, sodium hydroxide is added into the bismuth separation liquid obtained in the step d, PH is adjusted to be 10 to 11, bismuth in the liquid is hydrolyzed, bismuth slag is obtained after filtration, and metal bismuth is obtained after reduction. The method has the following beneficial effects that the method is simple, operation is convenient, and the bismuth recycling rate and the bismuth recycling purity are high.
