已有的研究确认了无机盐对孔雀石直接浮选所起的相转移活化作用，本试验采用氨气敏电极，测定了硫酸铵、氯化铵、硫酸铁铵等无机铵盐在孔雀石浮选过程中氨浓度变化情况研究结果表明：无论是硫酸铵、氯化铵、还是硫酸铁铵，它们在孔雀石黄药浮选的始终，铵离子浓度保持不变，而只是在浮选过程中发生变化，参与了矿物、药剂之间的反应，从而可断定：无机铵盐在孔雀石的纯矿物浮选中，表现为一种“相转移催化剂” Some studies have confirmed the inorganic salt on the malachite direct flotation phase transfer activation, the test using ammonia gas sensing electrode, measured ammonium sulfate, ammonium chloride, ammonium ferric sulfate and other inorganic ammonium salt in malachite float Changes in ammonia concentration in the process of selection  The results show that: whether ammonium sulfate, ammonium chloride or ammonium ferric sulfate, malachite bezoar in their flotation always, ammonium ion concentration remains unchanged, but only in the flotation process In the mineralogy, the reaction between the agents, which can be concluded: inorganic mineral salts in pure mineral flotation of malachite, the performance of a “phase transfer catalyst ”
