【Abstract】 The chemical composition, mineral structure and thermal physical performance of Yanfeng dolomite have been researched by chemical analysis, X ray diffraction analysis, optical microscope analysis, SEM analysis, electron micro probe analysis and differential thermal analysis. The results show that the Yanfeng dolomite mineral is a kind of high calcium dolomite. Because of its high purity and fine crystal, it is the ideal raw material for producing high calcium magnesite clinker. Experiments show that the bulk density of synthesized high calcium magnesite clinker is more than 3.30g/cm 3 when the synthesized temperature is at 1650℃.更多还原
