摘　　要：采用微波焙烧高硫铝土矿脱硫。用X射线衍射仪和常规的化学分析方法分析高硫铝土矿中各种矿物物相组成特征,最主要是得出其中硫的存在形式;运用X射线衍射仪、扫描电子显微镜、高频红外碳硫仪检测仪器,分析微波脱硫后的物相组成。参阅已有的文献资料,以热力学理论分析为基础,利用化学物相分析和物理物相分析,探究了微波焙烧脱硫热力学机理,提出了脱硫机理。Microwave is used to roast the high - sulfur bauxite. Using the XRD and conventional chemical analysis methods to analyze the composition characters of various mineral phase in the high - sulfur bauxite, the most important of all is to obtain the exiting form of sulfur in it; the phase composition has been analyzed by XRD, SEM and high frequency infrared carbon - sulfur analyzer. Refer to the existing literature and on the base of the theory of thermody- namics analysis, the mechanism of thermodynamic is explored and the desulfuration mechanism is presented using the chemical and physical phase analysis.
