<p>Arsenic removal from copper ores/concentrates is one of the most important issue in mining industries. Under the national project led by JOGMEC, Kyushu University and Sumitomo Metal Mining Co. Ltd. has carried out systematic research on the arsenic removal from copper concentrates, including the heat treatment-magnetic separation, flotation and bioleaching. The flotation studies were carried out mainly on chalcopyrite as a main copper sulfide and enargite as an arsenic containing copper sulfide. Enargite was separated from chalcopyrite by flotation by combining potassium amyl xanthate (PAX) and hydrogen peroxide. The resultant arsenic-rich “dirty” concentrates and/or arsenic-containing copper concentrates were subjected to the magnetic separation as well as bioleaching processes. After the heat treatment, chalcopyrite exhibited magnetic property whereas enargite did not. This difference enabled the magnetic separation of the two minerals. Bioleaching was carried out with the addition of activated carbon to improve the copper dissolution as well as As immobilization.</p>
