Abstract

Direct to blister (DTB) accounts for a significant process for copper making due to its simplified process chain and the production of a single stable SO2-concentrated off-gas. In this study, the phase equilibria of iron silicate slags in the Cu-Fe-Si-S-O system at controlled atmosphere were, for the first time, experimentally investigated in the spinel primary phase field. The liquidus temperatures were quantified, including the equilibrium “Cu2O” content as well as the solid solutions in spinel.
