Abstract:Beneficitation test of a low grade iron-bauxite from Henan in this paper: On the basis of the technological mineralogy, selection of iron concentrate by preferential magnetic separation, and magnetic separation tailings are classified and floated to select aluminum concentrate.Once roughing flotation,once concentration flotation and once scavenging flotation to get the aluminium concentrate.Different conditions were tested in the coarse section and the optimal conditions were selected. Closed circuit tests were carried out on the basis of the best condition test, a good index of iron concentrate TFe content 60.48%, aluminum concentrate Al2O3 content 65.46% and A/S 6.32 was obtained.
