High smelting temperature of phosphate ore and low activity of the slag lead to energy-extensive consumption and large solid waste generation in the yellow phosphorus industry. Micronutrient-bearing cosolvents were added to the reduction smelting process of phosphate ore to reduce the smelting temperature and increase the activity of slag in the current work. Thermodynamic analysis demonstrated that B₂O₃ and K₂O as cosolvents can decrease the melting temperature, promote the liquid phase formation and reduce the slag viscosity. In addition, cosolvents had no unfavorable effect on the reduction volatilization of phosphate ore, and the volatilization ratio of phosphorus was > 97 wt.% at 1550°C for 1 h. In this case, the value of slag was enhanced with the addition of cosolvents, and the activation ratios of micronutrients were > 90%. Resultantly, no solid waste was generated since the activated slag can be regarded as a favorable ingredient for the crop fertilizer.

磷矿石的高熔炼温度和炉渣的低活性导致黄磷行业能源消耗大量，产生大量固体废物。在目前的工作中，将含微量元素的助溶剂加入到磷酸盐矿石的还原熔炼过程中，以降低熔炼温度并提高炉渣的活性。热力学分析表明，B ₂ O ₃和K ₂O作为助溶剂可以降低熔融温度，促进液相形成并降低炉渣粘度。另外，助溶剂对磷酸盐矿石的还原挥发没有不利的影响，并且磷的挥发比在1550℃下1小时＞ 97wt。％。在这种情况下，添加助溶剂可提高矿渣的价值，微量营养素的活化率> 90％。结果，没有产生固体废物，因为可以将活性炉渣视为农作物肥料的有利成分。
