摘　　要：在高温条件下,利用熔融浸渍法,对贵州万山地区钾长石进行提钾工艺研究,全面探讨助熔剂的阴离子及阳离子对钾提取率的影响,最终选定NaCl为最佳助熔剂。正交实验数据表明,钾长石提钾的较佳工艺条件为:焙烧温度900℃、焙烧时间120 min、m(钾长石)∶m(NaCl)=1.5,钾的提取率为87.97%。Under high temperature conditions, Guizhou Province Wanshan region extracting potassium feldspar research process was studied comprehensively by melt impregnation method, which influenced anions and cations of flux on potassium extraction rate. The final selection was NaC1, and orthogonal experiment data showed that potassium feldspar mention better conditions were calcination temperature 900℃, calcination time 120 min, re（feldspar） ：m（NaC1） = 1.5. Potassium extraction rate was 87.97%.
