The Equilibrium diagram of the system nickel sulfide-copper sulfide-iron sulfide is determined by thermal analyses and microscopic examinations, and a new diagram is proposed as shown in Fig. 8. There are four reactions in this system.
Liq.+(FeS)=γ-Ni3S2+Cu2S at 880°C
(FeS)+γ-Ni3S2+Cu2S+(FeS)2S·Ni3S2 at 575°C
γ-Ni3S2=(FeS)2·Ni3S2+Cu2S+β-Ni3S2 at 495°C
β-Ni3S2=(FeS)2·Ni3S2+Cu2S+α-Ni3S2 at 477°C
