| Abstract: | The calcium sulfide was prepared by reduction roasting method with coal as reducing agent, using phosphogypsum as the main material. This paper studied the influence of anthracite, the quality of phosphogypsum ratio, fineness of material, sintering temperature and sintering time on the reduction rate of calcium sulfide in the phosphogypsum. Using coal as reducing agent the optimum condition of preparing calcium sulfide by reducing phosphogypsum was determined. |
