| Abstract: | Taking a low-grade bauxite in Guxian, Shanxi Province as the research object, the properties of raw ore and flotation desilication performance were studied. The effect of grinding fineness and dosage of reagent on flotation index was investigated, and appropriate technological parameters were determined. Al2O3 content of raw ore was 58.47%, SiO2 content was 19.75%, A/S was 2.96 low-grade bauxite. Through closed-circuit flotation desilication test of "one roughing, two refining and one sweeping", the aluminium concentrate yield was 60.64%, A/S was 6.11, and Al2O3 recovery was 69.5. 2%; tailings A/S is 1.41. |
