Secondary Copper Converter Dust Metal .

Flue dust was leached at room temperature with an alkaline solution of (NH4)2CO3 and NH4OH to solubilize ZnO and Zn metal. Some copper, lead, tin, and most of the zinc were dissolved in the leach step. Copper, lead, and tin were recovered in the cement product. The Zn in the filtrate was precipitated by pH adjustment to neutral using CO2 injection.
