摘　　要：综述白钨与含钙脉石浮选分离抑制剂的研究进展。无机抑制剂在白钨浮选中应用广泛,其抑制机理研究较多,机理解释相对统一,而高分子有机抑制剂具有较强的抑制能力,较好的选择性,但抑制机理暂不明确。因此开发具有特效作用的小分子和高分子抑制剂,查明起选择性抑制作用的关键基团及其作用机理,对白钨与含钙脉石浮选分离有重要意义。Research development of the depressants for flotation separation of scheelite and calcium -bearing gangue are reviewed. Inorganic depressants are widely used in scheelite flotation, of which the mechanism has been well studied with a uniform explanation. Polymer organic depress-ants possess strong inhibiting ability and high selectivity. However, the inhibitory mechanism of polymer organic has not been fully revealed. Thus, developing small molecules and polymer organic depressants with special effects, and studying the action mechanism of organic depressants are sig-nificant for the flotation separation of scheelite and calcium - bearing gangue.
