萤石不难用油酸浮选,但由于它和方解石之间可浮性差别很小,通常二者之间分离十分困难。本文介绍了使用混合药剂Na_2SiO_3+Al_2(SO_4)_3作为抑制剂,选择地抑制方解石机理的研究结果。矿样采自埃及东部沙漠,具有相当纯度的萤石及方解石晶体;试验用的粒度为-100+150网目。所用 Fluorite is not difficult to oleic acid flotation, but because of its flotability difference between calcite is very small, usually the separation between the two is very difficult. This paper presents the results of the study on the selective inhibition of calcite mechanism by using a mixture of Na_2SiO_3 + Al_2 (SO_4) _3 as inhibitor. The ore samples were collected from the deserts of eastern Egypt and had fairly pure fluorite and calcite crystals. The test grain size was -100 + 150 mesh. Used
