主　　题：binary system Cu2S-MoS2 bath smelting process solubility eutectic molybdenite 

摘      要：A novel method,bath smelting process,was developed to treat molybdenite concentrate aiming at the existing problems of traditional *** understand the dissolving behavior of MoS2 in white matte,the binary phase diagram of Cu2S-Mo2S was measured by the cooling curve *** result shows that this system is a simple binary eutectic with a eutectic temperature of（1117.0±3.0）℃ and a eutectic composition of（1.70±0.20）% MoS2 in mass *** the MoS2 addition exceeds 4.48%,MoS2 and Cu2S can form the ternary compound containing CuMo2S3 or *** the temperature range of copper smelting,1200-1300℃,molybdenite can dissolve in the cuprous *** 1200℃,the solubility of molybdenite can reach 14.8%.
