The distribution of Ag, Co, Ni, Zn, Sn, Pb, As, Sb and Bi between calcium ferrite slag and metallic copper was measured at 1250°C under controlled CO-CO2 atmospheres, and the distribution measurements of Zn, Sn, Pb, As and Bi were also carried out for iron silicate slag.
By considering the relationship between the distribution coefficient and the oxygen potential, it was expected that the minor elements are present in the slags in the following forms: CuO0.5, AgO0.5, CoO, NiO, ZnO, SnO (SnO2 in the range of high oxygen potential), PbO, AsO1.5, SbO1.5, BiO1.5
The dissolutions of arsenic and antimony in ferrite slags are much more than in silicate slags. Lead and zinc are more soluble in silicate slags than in ferrite slags.
