本研究提出了反射炉熔态还原磷酸盐矿石制取P_2O_5的新工艺。在实验室条件下研究了焦炭与煤还原磷矿石的动力学,考察了碱度及温度对于还原反应速度及还原度的影响,结果表明还原速度及还原度随碱度与温度的增高而增大。根据X射线衍射分子及显微镜物相分析
In this study, a new process for preparing P_2O_5 from the reverberant furnace molten state phosphate ore was proposed. The kinetics of reduction of phosphate rock by coke and coal was studied under laboratory conditions. The effects of alkalinity and temperature on reduction rate and reduction rate were investigated. The results show that reduction rate and reduction degree increase with increasing alkalinity and temperature Big. Based on X-ray diffraction and microscope phase analysis
