Processing method of copper anode slime
FIELD: metallurgy. SUBSTANCE: method includes antimony and lead leaching from copper anode slime in a solution containing 50-200 g/dm 3 of glycerin, 50-100 g/dm 3 of alkali and a reducing agent, in an amount that provides the system oxidation-reduction potential more positively than +0.8 V at a temperature of 70-90°C for 2-3 hours. Thus lead from the leach solution is educed by known methods.

It is known that the presence of catalytic metals (e.g., copper, nickel, zinc, iron, and aluminum and their salts) and the temperature range of 450-750°F can promote dioxin and furan formation (e.g., Stieglitz and Vogg 1987; Vogg et al. 1992). Traditionally, many APCDs are operated within that temperature range to avoid acid-corrosion problems.
