SEPARATION OF TOXIC HEAVY METALS 443 Sulfide precipitation processes to remove heavy metals have gained con siderable industrial importance (57). The treatment of mine drainage (8) and gold mine wastes (9) by Na,S precipitation and of metal finishing wastewaters (with and without chelating agents) by FeS precipitation (6) has been reported in the literature.

The selective separation and recovery of copper, cadmium, zinc, and nickel from a polymetallic solution with sulphide precipitation using thioacetamide have been investigated. Selective metal sulphide precipitation was studied as a function of pH, contact time, and temperature. The results showed that it was possible to separate metals by accurately controlling the pH and temperature.

Sulfide precipitation with Na 2 S is found to be highly effective to obtain a high degree of separation of heavy metal cations (Cd, Zn, Cu, and Pb) and of the oxyanions of arsenic and selenium from complex wastewaters. The metal separation characteristics are evaluated with a dilute synthetic mixture and with an actual copper smelting plant wastewater.
