Abstract

Abstract

Grinding is the prerequisite for successful flotation separation. Based on the grinding test, the single mineral flotation test, the wettability test and the scanning electron microscope test, the effects of ceramic rod grinding and ceramic ball grinding on surface morphology and flotation behavior of calcite were studied. The results showed that calcite mineral particles treated by ceramic ball grinding have higher hydrophobicity, better flotation recovery, greater flatness and elongation, and smaller roundness and relative width than those treated by ceramic rod grinding.
