<p>Silver is recovered from electrolytic copper refinery slimes containing, in addition to silver, one or more of the elements Se, Te, Pb, Sb, Sn, As, Bi, Zn, Cu, Au, Ni. Fe, among others. A slurry is formed of the slimes in a hydrochloric acid solution which is agitated, during which excess chlorine gas is added to solubilize substantially all of the elements present, the silver being substantially quantitatively converted to silver chloride to form a silver-enriched residue. The residue is thereafter separated from the solution and the silver then recovered from the residue.</p> |
