中文摘要

通常采用硫化–黄药法对孔雀石进行回收，由于矿石中伴生方解石的存在，往往导致铜的浮选指标不理想，出现这种现象的重要原因是孔雀石和方解石的溶解组分会在两种矿物表面发生交互影响，从而影响其浮选行为。本文研究了孔雀石和方解石的溶解组分对这两种矿物的浮选行为和表面特性的影响。浮选试验表明，在孔雀石浮选矿浆中加入方解石的溶解组分后，孔雀石的回收率会降低，反之，孔雀石溶解组分的存在能够增加方解石的回收率。溶解和吸附检测、Zeta电位测定、X射线光电子能谱、傅里叶变换红外光谱和飞行时间二次离子质谱表征结果表明，方解石溶解液中的钙组分会吸附在孔雀石表面，并阻碍硫化钠与孔雀石表面进行作用，从而导致异戊基黄原酸钠在孔雀石表面难以有效吸附；同样地，孔雀石溶解液中的含铜组分会吸附在方解石表面，为硫化钠和异戊基黄原酸钠在方解石表面的吸附提供了活性位点。

Effect of dissolved components of malachite and calcite on surface properties and flotation behavior

Abstract

Abstract

In general, malachite is recovered via sulfidization–xanthate flotation, although many unsatisfactory flotation indexes are frequently obtained as a result of the presence of associated calcite. This phenomenon occurs because the dissolved components of malachite and calcite affect the flotation behavior of both minerals. In this study, the effect of the dissolved components derived from malachite and calcite on the flotation behavior and surface characteristics of both minerals was investigated. Flotation tests indicated that malachite recovery decreased when the calcite supernatant was introduced, while the presence of the malachite supernatant increased the recovery of calcite. Dissolution and adsorption tests, along with zeta potential measurements, X-ray photoelectron spectroscopy, Fourier transform infrared spectrometry, and time-of-flight secondary ion mass spectrometry demonstrated that the Ca species in the calcite supernatant were adsorbed on the malachite surface, which hindered the interaction of Na₂S with malachite, thereby resulting in the insufficient adsorption of sodium isoamyl xanthate (NaIX) on the surface of malachite. By contrast, the Cu species in the malachite supernatant were adsorbed on the calcite surface, and they provided active sites for the subsequent adsorption of Na₂S and NaIX.
