摘　　要：首先在哈里蒙管中研究了蓝晶石类同质异相矿物的浮选规律及行为。进一步应用量子化学ＣＮＤＯ／２法计算了捕收剂在矿物上吸附的能量变化和矿物表面原子的电荷分布密度，并根据量子化学计算结果成功地解释了蓝晶石类同质异相矿物的浮选规律。In this paper, the flotation rule and behavior of kyanite一group polymor-phous minerals were studied in modified Hallimond tube in detail,Further-more, the energy change of collector/mineral systems before and after ad-sorption and the net charge densities of the atoms on the minerals surfaceswere calculated by use of quantum chemistry,The flotability of the mine-rals was successfully explained.
