This paper studied the removal of silicate by reverse flotation from bauxite ore from Guizhou province which contains 61.55%Al2 O3 ,10.99%SiO2 ,and of which the ratio of Al2O 3 to SiO 2 is 5.60.The optimum reagent system was determined by conditional tests .According to its comminution characteristics ,the final process of staged-grinding and staged -flotation was used , and a concentrate with a recovery of 80 .33%and a A/S ratio of 10 .07 was obtained.
