摘要/Abstract

摘要： 研究了黄铜矿、铁闪锌矿自诱导和外控电位浮选的基本行为。结果表明，黄铜矿在较宽的pH范围内均可实现自诱导浮选，并且通过外控电位可以控制它的浮选行为；铁闪锌矿在酸性条件下可实现自诱导浮选，通过外控电位也可以控制它的浮选行为；碱性条件下铁闪锌矿不能实现自诱导浮选，通过外控电位也难以改变它的浮选行为。通过测量循环伏安曲线，分析了两种矿物表面氧化形成的产物，元素硫是主要的疏水体。

Abstract: The basic behavior of self-induced flotation and controlled electric potential flotation of chalcopyrite and marmatite were investigated in this paper. It was shown that chalcopyrite exhibit good self-induced floatability in wide pH range and its flotation behavior can be controlled by the externally controlled voltages. Marmatite can realize self-induced floatability in acidic condition and its self-induced floatability can be controlled by the externally controlled voltages. While marmatite can not realize self-induced floatation and hardly improve its floatability by varying externally controlled voltages in alkaline condition. Reaction products by the surface oxidation of two minerals were studied by measuring the cyclic voltammetric curves, where the elemental sulfur was the main hydrophobic entity.
