In light of characteristic of low quality feldspar ores in Wanzai County,Jiangxi Province,steel ball was taken as grinding medium,and selective grinding could make impurity separate from feldspar effectively. Through the flow of flotation-desliming-high gradient magnetic separation,the feldspar Concentration 1 was obtained with the yield of 70.19 %,containing Fe2O3 0.17 % and TiO2 0.07 %. The feldspar Concentrate 1 could meet the quality requirement of high-grade construction ceramic. And the slime that was deslimed in the flow was also separated and recovered; the feldspar Concentration 2 was obtained with the yield of 13.18 %,containing Fe2O3 0.31 % and TiO2 0.17 %. The feldspar Concentrate 2 can be used for raw material of low-end ceramic. And gangue,with the yield of 16.63 %,was thrown away in this flow,the separating efficiency was high. Employing this flow could also bring high economy benefit and low influence of pollution to environment. 展开更多
