The transformation of selenium-containing phases in copper anode slimes during the leaching process was investigated based on the Eh–pH diagram, leaching efficiencies of metals, and characterization of the residues produced during leaching. The leaching efficiency of selenium increases slowly to 17.7% in the first 50 min and then more rapidly to 98.3% in the next 110 min. The Eh–pH diagram indicates that elemental selenium is an intermediate product of the oxidation of selenide to selenite. The… CONTINUE READING
