Abstract
Oxygen pressures in a copper flash smelting furnace were measured by means of the following galvanic cell: Fe, FeO/ZrO2 + MgO/barO in slag or matte. Measured oxygen pressures were normalized to 1523 K with respect to the reaction: 4 FeO(l) + O2(g) = 4 FeO1.5(l). Vertical and horizontal variations of normalized oxygen pressures in the reaction shaft and in the settler were studied. The equilibrium relation between normalized oxygen pressure and the ratio of ferric to ferrous oxide content in the furnace slag was confirmed, and the activity coefficient ratio of these oxides was determined.
