Abstract

Abstract

This paper aims to study the chemical composition, liberation degree, interlocking relationship and surface morphology of the main minerals in high-sulfur bauxite. The high-sulfur bauxite ore in Guizhou, China was taken as the study object. By adopting the means of elemental analysis, mineral liberation analyzer (MLA) and scanning electron microscope (SEM), the research came to the following findings. The contents of Al₂O₃, S and SiO₂ in ore were 62.71%, 3.37% and 9.94%, respectively. The contents of Ce and Ga in ores were 121.0 g/t and 40.3 g/t, respectively. Pyrite was widely distributed in the ore, closely associated with diaspore, with fine embedded particle size. When the grinding fineness was -0.075 mm accounting for 77%, the liberation degrees of diaspore and pyrite were 14.10% and 71.20%, respectively. Because the liberation degree of pyrite was high, and the liberation degree of diaspore was low, the flotation process of 'stage grinding-stage separation' could be used for desulfurization.
