CO allowing the direct contact between iron oxide and solid carbon. Bafghi (1993) found that the rate of reduction of FeO increased with the evacuation of CO (produced as a product of FeO/Fe 2O 3 reduction). The occurrence of CO enhanced the agitation and thus promoted the reduction at low concentration of FeO (2 ) but acted as a barrier

The effect of iron on the solubilities of Co and Ni in silicate melts was determined at a wide range of oxygen fugacities (from 10 -8.1 to 10 -12.6 atm) and at temperatures ranging from °C. Four different systems were studied. In system A an FeO-free silicate of anorthite diopside eutectic composition was equilibrated with pure Co- or pure Ni-metal.
