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
