| 摘 要： | 磨矿是浮选分离成功的前提。通过磨矿试验、单矿物浮选试验、润湿性测试、扫描电镜测试，研究了陶瓷棒磨与陶瓷球磨，不同磨矿方式对方解石颗粒表面形貌及浮选行为的影响。试验结果表明，经过陶瓷球磨处理后的方解石矿物颗粒相较于经过陶瓷棒磨处理后的方解石矿物颗粒有着更大的疏水性，更好的浮选回收率，更大的扁平率与伸长率，以及更小的圆度和相对宽度。

| 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. |
