2019-2-21 · often present in industrial smelting, such as CaO, MgO, and Al 2 O 3. Distributions of minor elements (Ag, Au, Pb, Sb, As, Zn, Pd, Pt, and Rh) in copper matte-slag system have also been extensively studied [5, 7-10]. The kinetics of matte smelting can be divided into two major parts: oxidation of chalcopyrite into matte
