研究了产在火成磷酸盐矿床中的不同磷灰石的性质。考查了产在磁铁橄磷岩、风化的磁铁橄磷岩和辉岩中的原生磷灰石和次生磷灰石的可浮性。还对以下脉石矿物进行了研究:石英、辉石、蚀变的云母(蛭石)、方解石和白云石。测定了上述矿物的Zeta电位与pH、pCa和pMg之间的关系曲线。还用改进的哈里蒙德浮选管研究了pH、油酸捕收剂用量和抑制剂玉米淀粉用量对矿物可浮性的影响。
The properties of different apatites produced in pyroxene phosphate deposits were investigated. The flotability of primary apatite and secondary apatite produced in magnetite, weathered magnetite and pyroxene was examined. The following gangue minerals have also been studied: quartz, pyroxene, altered mica (vermiculite), calcite and dolomite. The Zeta potential of the above minerals was measured as a function of pH, pCa and pMg. The effects of pH, the amount of oleic acid collector and the amount of corn starch as inhibitor on mineral floatability were also investigated using an improved Halimonde flotation tube.
