摘要: 重点综述了闪锌矿活化与去活化的研究进展,讨论了闪锌矿活化离子的来源,指出闪锌矿活化受矿浆电位、pH值、活化剂浓度和晶格缺陷等因素影响,铜氨络离子对闪锌矿及铁闪锌矿具有良好的活化效果,能降低选矿药剂成本,改善锌精矿质量;去活化作用通过清除闪锌矿表面活化层或在其表面生成亲水薄膜实现;从回水利用、矿物的内外部环境和新药剂等方面预测了多金属硫化矿石的选矿理论与实践的发展方向.

Abstract: The activation and deactivation of sphalerite flotation were reviewed. The sources of ions which could activate sphalerite flotation were discussed. The mechanism of activation is affected by pH value, the potential of slurry, concentration of the activator and lattice imperfection. Sphalerite and marmatite are effectively activated by ammoniacal copper complex ion, which can lower the cost and improve the quality of zinc concentrate. The deactivation will be generated by removing the activate ions or hydrophilic film coating on sphalerite surface. And the research directions of theory and technologies of flotation for polymetallic sulphide ores based on the use of recycled water, inside and outside environmental of minerals and new flotation agents were also predicted.Key words: sphalerite; flotation; activation; deactivation; unavoidable ions
