AbstractA hydrometallurgical process using sulfuric acid leaching of copper smelter flue dust at 120-130 degrees C in the absence of oxygen has been developed to remove arsenic to prevent environmental pollution and to recover bismuth and other valuable metals. About 90% of the arsenic and less than 10% of the copper dissolved into the leaching solution. Most of the copper remained in the residue as cupric sulfide. Arsenic and iron were removed from the leaching solution by oxidation and precipitation as ferric arsenate. Bismuth in the residue was extracted in a solution containing a mixture of sulfuric acid and sodium chloride; then, more than 90% of the bismuth was recovered from the leaching liquors as a product of Bi sponge by cementation with iron powder.
