The physicochemical reaction in the roasting process is further analyzed, in which the chemical reaction is the REDOX reaction of MoS2 as well as the reactions of molybdenum trioxide with impurity... temperature of molybdenite trioxide is 600 °C, so the significant mass change in the high temperature range is mainly attributed to the sublimation of molybdenum trioxide. In order to eliminate......

, and it is evident that sulfate roasting effect has a positive correlation with ferric sulfate concentration, because more ferric sulfate results in more sulfur trioxide, which can react with zinc ferrite...% as the temperature continues to increase. It may be attributed to the fact that the ferric sulfate is more easily to transform into sulfur trioxide at higher temperatures, moreover, the sulfate reactions can......
