【摘要】：白钨矿与萤石、方解石等含钙矿物表面性质相似,可浮性相近,在浮选体系中难以实现白钨矿与它们的高效分离和有效回收,因此在研究白钨选矿浮选捕收剂的同时,开展对含钙脉石矿物高效分离抑制剂的研究至关重要。文章综述了近年来白钨矿与含钙脉石矿物分离抑制剂的研究现状,详细阐述了多种无机抑制剂和有机抑制剂的抑制机理和应用,并结合当前白钨矿与含钙矿物抑制剂的研究进展,认为开发对含钙矿物具有高效抑制性能的药剂引入特性基团增强抑制剂的亲水性,能达到提高其选择性的目的,最后探讨了抑制剂研究的新方向。
[Abstract]:The surface properties and floatability of scheelite and fluorite, calcite and other calcium bearing minerals are similar, so it is difficult to realize the efficient separation and effective recovery of scheelite from them in flotation system. Therefore, the flotation collector of scheelite is also studied. It is very important to study the high efficiency separation inhibitors of calcium-bearing gangue minerals. This paper reviews the research status of scheelite and calcium-bearing gangue mineral separation inhibitors in recent years. The inhibition mechanism and application of various inorganic and organic inhibitors are described in detail, and the research progress of scheelite and calcium-bearing mineral inhibitors is also reviewed. It is considered that the hydrophilicity of the inhibitor can be improved by introducing the characteristic group to enhance the hydrophilicity of the inhibitor. Finally, the new research direction of the inhibitor is discussed.

【正文快照】： 我国的白钨矿床具有钨品位低、嵌布粒度细等特点,白钨矿(Ca WO4)、萤石(Ca F2)、方解石(Ca CO3)是白钨矿床中三种主要含钙矿物,其中白钨矿和萤石是具有工业利用价值的含钙矿物,方解石由于含量和价值低而作为脉石矿物。白钨矿与含钙脉石矿物分离时主要选矿方法是浮选。对含钙脉
