摘　　要：以宁国钾长石矿为主要原料 ,采用共烧结工艺 ,研究了用CaCl2 做添加剂与钾长石共烧结温度、时间、CaCl2 用量对溶出率的影响 ,确定了共烧结最佳参数。同时 ,通过XRD表征方法 ,对原矿物相及水浸渣物相进行了研究 ,探讨了共烧结反应机理。实验结果表明 ,钾长石中K2 O溶出率可达 95 %。In the presence of CaCl 2 this paper has studied the mutual sintering process of K-feldspar,which come from Anhui Ningguo. The recovery rate affected by mutual sintering temperature and time, quantity of CaCl 2 and the optimal technological parameters were determined. The K-feldspar powder and the leaching residues were analyzed by XRD. As comparison of the two XRD patterns, the reaction mechanism was studied. Test results show a recovery of up to 95% of potassium contained in potassium concentrates.
