摘要

摘要:
滑石是一种含镁硅酸盐矿物，常与金属硫化矿共伴生。在硫化矿浮选中，滑石常因其较好的天然可浮性而上浮进入精矿中，导致精矿中镁含量超标，从而影响后续的冶炼。有机药剂是一类常见的滑石抑制剂，对滑石具有较好的抑制作用。为此，全面总结了硫化矿浮选过程中有机抑制剂对滑石的抑制机理和研究现状，指明该类抑制剂主要是通过其分子中的羟基、羧基和疏水烃链等与滑石表面的氧原子、金属离子或滑石表面的疏水位点之间形成氢键、化学作用或疏水作用，从而吸附于滑石的表面，降低滑石表面的疏水性，实现对滑石的抑制。

Abstract:
Talc is a magnesium−containing silicate mineral, which is often associated with metal sulfide ore. In the flotation of sulfide ore, talc often floats into the concentrate due to its excellent natural floatability, resulting in excessive magnesium content in the concentrate, thus affecting the subsequent smelting. Organic reagents are of common talc depressants, which have the outstanding depressant effects on the talc. Therefore, the depressant mechanism and research progress of organic depressants on talc in the flotation process of sulfide ore were comprehensively summarized. It was pointed out that these depressants mainly form hydrogen bonds, chemical interactions or hydrophobic interactions between hydroxyl groups, carboxyl groups, or hydrophobic hydrocarbon chains in the molecules and oxygen atoms, metal ions or hydrophobic points on the surface of talc. Therefore, they were adsorbed on the talc surface, to reduce the hydrophobicity of talc surface, and realize the depressant for talc.
