摘　　要：黑钨细泥采用重选法回收指标不理想,为提高黑钨细泥的回收利用率,对黑钨矿浮选进行了大量的深入研究。介绍了黑钨矿表面结构和溶液离子对黑钨矿浮选影响的研究现状,黑钨矿组成独特,其表面结构和化学组成存在较大差别。锰铁比不同的黑钨矿,其可浮性存在差异,与药剂作用机理相当复杂,不同药剂的作用机理不尽相同。溶液离子来源广泛,对浮选过程具有较大影响,可活化矿物促进药剂在其表面的吸附,抑制矿物减弱药剂在其表面的吸附,与浮选药剂相互作用而消耗药剂。因此,研究黑钨矿表面结构特性以及溶液离子的影响有助于精准化控制黑钨浮选条件。This paper introduces the research status of factors affecting wolframite＇s surface structure and solution ions on wolframite flotation. Wolframite＇s composition is unique with different surface structures and chemical compositions. The floatability of wolframite changed with different Fe/Mn ratios. The agent mechanism is very complicated and still surviving different opinions. Solution ions have great influence on the flotation process with its wide source. he solution ions can make the mineral activating and promote adsorption of reagents on the surface, or inhibited mineral and reduce adsorption of reagents on the surface, or effect with the flotation agent and consumption of it. Wolframite＇s surface structure and solution ions are important factors affecting the flotation of wolframite. Studies of wolframite＇s surface structure characteristics and the impact of solution ions are helpful to precise control wolframite flotation conditions.
