In the presence of CaCl2 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 CaCl2 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.
