However, the effective utilization of this mineral is still under infant.
Fine liberation size makes it unavoidable to encounter slimes during processing of diasporic bauxite. Through flotation separation, diaspore can be disseminated in course particles among the aluminosilicates or the dominant presence of gangue particles traps fine diaspores in the slime (Yuhua et al., 2011). Therefore, reagent (collectors or ...
ﬂotation of diaspore bauxite. Due to the dissolution of diaspore bauxite, the quality of fresh water, the mechanical wear and other reasons, a certain number of iron ions in backwater will be presented. The concentration of iron ions in backwater was 1 10−5 mol/L measured by ICP. Diaspore bauxite mainly consists of diaspore and kaolinite ...
