铝土矿矿物磨矿粒度分析表明 ,矿物之间存在明显的可碎性差异。高岭石等含硅矿物易泥化 ,影响浮选指标。在浮选工艺研究的基础上 ,提出了两段两闭路磨矿和返回中矿直接进入二段磨矿回路磨矿流程 ,获得了理想的粒度特性。 Bauxite minerals grinding particle size analysis showed that there are significant differences between the friability of the friable. Kaolinite and other silicon-containing minerals easily muddy, affecting the flotation index. Based on the research of flotation process, two sections of two closed-circuit grinding and returning medium-sized mines are directly entered into the second-stage grinding circuit grinding process, and the ideal particle size characteristics are obtained.
