Abstract
This investigation is on the leaching of copper-smelter flue dust to recover copper and separate deleterious components for recovery or safe disposal. Leaching of copper-smelter flue dust with dilute sulfuric acid solution, containing small amounts of chloride and fluorine, has extracted more than 90 pct of the copper, arsenic, and cadmium, and 80 pct of the bismuth. Selective stripping of arsenic and bismuth was accomplished with water, and molybdenum was stripped with ammonia. The copper-rich solutions produced should be suitable for recycle to the copper smelter.
