摘要
通过分析去离子水浸泡矿石后矿浆中的难免离子组成,研究矿浆中发生变化较大的Ca2+,Mg2+,Fe2+,Fe3+,Cu2+,Zn2+和Al3+等离子对黄铜矿和方铅矿浮选的影响。发现这些金属离子在用乙基硫胺酯做捕收剂的体系中对黄铜矿的浮选基本没有影响,而对方铅矿浮选的影响分成3类,起活化作用的Cu+,起抑制作用的Al3+,Fe3+,Fe2+,Zn2+和Cu2+以及基本不起作用的Mg2+和Ca2+。对阳离子的抑制机理进行了探讨。
The influence of metal cations in the pulp, such as Ca^2＋ , Mg^2＋ , Fe^2＋ , Fe^3＋ , Cu^2＋ , Zn^2＋ and Al^3＋ etc. , to the chalcopyrite and galena floatability based on the composition analysis of the ore pulp dipped in the deioned water is studied. It is found that the chalcopyrite floatability is not influenced by these cations with the isopropyl thionocarbamate as collector, and the cations can be divided into three types according to their effect on the galena floatability, as activator such as Cu＋ , as depressant such as Al^3＋ , Fe^3＋ , Fe^2＋ , Zn^2＋ and Cu^2＋ , unaffeetive such as Mg^2＋ and Ca^2＋.
