白钨矿与含钙矿物浮选分离抑制剂研究:综述

摘要: 由于黑钨矿的枯竭,钨开采的重点已逐渐转移到白钨矿。然而,分离相关矿物(如磷灰石、萤石和方解石)和白钨矿是一项挑战,因为它们的表面物理化学特性与白钨矿相似。幸运的是,研究人员通过使用抑制剂在分离白钨矿的矿物方面取得了实质性进展。本研究回顾了无机抑制剂在从含钙矿物中获取钨资源的应用和抑制机制;总结了新的有机抑制剂在从含钙矿物中获取钨资源的应用和相关机制。在客观评估了无机和有机抑制剂的优点和缺点后,提出了无机和有机抑制剂未来可能的研究方向,为开发白钨矿浮选抑制剂提供了理论基础。

 

Flotation separation depressants for scheelite and calcium-bearing minerals: A review

Abstract: Owing to the depletion of wolframite, the focus of tungsten extraction has gradually shifted to scheelite. However, separating the associated minerals (e.g., apatite, fluorite, and calcite) and scheelite is challenging because their surface physicochemical properties are similar to those of scheelite. Fortunately, researchers have made substantial progress in separating the minerals of scheelite by using depressants. This study reviews the application and inhibition mechanism of inorganic depressants in obtaining tungsten from its calcium-bearing minerals. The application of new organic depressants in obtaining tungsten from its calcium-bearing minerals and the associated mechanisms are also summarized. After an objective assessment of inorganic and organic depressants’ advantages and disadvantages, possible future research directions for inorganic and organic depressants are proposed. Herein, we provide a theoretical basis for developing scheelite flotation depressants.
