Abstract
Kidd Creek Copper Smelter Cottrell dust was characterized. It was 88% finer than 8μm and contained 21.3 % Zn, 26.2 % Pb, 10.6 % Cu, 1.8 % As, 1.4 % Sn, 0.6 % Cd and minor amounts of Bi, Co and In. The phases positively identified were: PbSO4, ZnO, ZnOFe2O3, ZnS, Cu2O, Cu2OFe2O3 and Cu3As. Processing in a 1.5 M H2SO4 leach followed by magnetic separation (0.69 T; 9.7 cm/s) of the leach residues achieved a 50–60% Zn and 60% Cd recovery to the leach liquor with over 40% Fe to the magnetic fraction and over 80% Pb, As, Sn to the non-magnetics.
