摘要
C类阴离子捕收剂试验结果表明,磷灰石呈现出比方解石更好的可浮性。磷灰石、方解石具有相同的表面活性质点Ca^(2+),由于解理面上Ca^(2+)密度不同导致矿物可浮性的差异。经计算,磷灰石表面Ca^(2+)密度为5.26个/nm^2,方解石为4.96个/nm^2,故磷灰石的可浮性高于方解石。
Test results show that the flotation of apatite is better than that of calcite when C anionic collectors are used. Apatite has the same surface active point Ca^(2+), as calcite. The density difference of Ca^(2+) on the cleavage plane between apatite and calcite leads to different floatability. The calculation confirms that the density of Ca^(2+) on the surface of apatite is 5.26/nm^2, while that on the surface of calcite is 4.96/nm^2, so the floatability of apatlte is better than that of calcite.
