| Abstract: | Current state of specularite beneficiation flowsheet in Lilou Mine, including grinding and classification processes, was introduced. The grinding efficiency was increased by reducing the mill feed size adopting a “more crushing and less grinding” principle, and parameters for grinding-classification operations were optimized. According to the effect evaluation, it can be concluded that size distribution of grinding products has been obviously improved. |

| Keywords: | specularite grinding-classification mill feed size efficiency optimization size distribution |
