Sorptive technology of extracting nonferrous metals from pit water

Abstract

Mine waters containing dangerous heavy metals are a significant environmental problem. Traditional methods of purification do not make it possible to completely eliminate impurities. In this work, the results of sorptive studies into the recovery of nonferrous metals from the mine water of a copper-zinc deposit are presented. Laboratory experiments for the selection of the optimal material and extended tests for the selected sample of a Lewatit TP 207 ion exchanger were performed. The possibilities of using ion exchangers to eliminate ions of heavy nonferrous metals are presented, and their capacity and selectivity indices relative to the sorption of nonferrous metals are determined. © 2013 Allerton Press, Inc.
