| Abstract: | The activity of sulfur in the Fe-S and Ni-S binary and the Fe-Ni-S ternary systems was investigated at 1250°C by equilibrating
molten mattes with gaseous mixtures of H2S and H2. From the sulfur activity data the activities of iron and nickel in the Fe-S and Ni-S binary systems as well as the activities
of FeS and Ni3S2 in the ternary system were calculated. Isoactivity diagrams are presented for S, FeS, and Ni3S2 in the Fe-Ni-S ternary system. Some comments are offered on the industrial problems of nickel slag loss and ferronickel separation. |
