Abstract

This study is focused on distribution of Co, Ni, Ag, Au, and Pd between molten copper and molten copper sulfide (‘white metal’) phases in copper converting conditions. The behavior of the elements selected was studied experimentally at 1300 °C and at various sulfur dioxide partial pressures (0.01, 0.05, 0.1, 0.5, and 1 atm). The experimental technique employed involves a high temperature equilibration followed by rapid quenching in ice water, with subsequent quantitative elemental analysis of the equilibrium phases with an electron micro probe analyzer. The distribution coefficients LMeCu/wm determined in this work can be arranged in the following sequence: Co < Ag < Ni < (Au, Pd).
