Abstract

Small quantities of Hg, Cu, Pb, Zn ions in waste-water are extracted by contacting the water with FeS or a substance contg. FeS and separating the metallic ions in the form of the metal sulphide from the water. Industrial waste-water is efficiently and economically purified by the removal of the heavy metal ions. The waste-water is pref. treated with pyrites or troilite.
