对三个高含黄铁矿的复杂铜-铅-锌矿样进行了各种试验室浮选试验,以探讨金属含量-金属回收率与诸如磨矿细度(比表面积)、pH值,浮选矿浆中的氧含量和氧化还原电位等影响浮选的参数之间的相互关系。试验表明,在最初浮选阶段之前(特别对于铜浮选),氧化还原电位的最佳调节可显著改善其选择性,氧化还原电位本身则取决于矿物粒度、pH值和调整剂。在工业应用中,通过改变磨矿条件可以减少矿泥的形成;通过测定和控制氧化还原电位可改善浮选动力学。 Various laboratory flotation tests were conducted on three complex pyrite-bearing complex copper-lead-zinc samples to investigate the effect of metal content-metal recovery in combination with factors such as grinding fineness (specific surface area), pH, The relationship between the oxygen content in the slurry and the redox potential affecting the flotation parameters. Experiments have shown that the best adjustment of the redox potential can significantly improve its selectivity before the initial flotation stage (especially for copper flotation), which itself depends on mineral particle size, pH and modifiers. In industrial applications, slime formation can be reduced by changing the grinding conditions; flotation kinetics can be improved by measuring and controlling the redox potential.
