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.

白钨矿和含钙矿物浮选分离抑制剂研究进展

随着黑钨矿的枯竭，提钨的重点逐渐转向白钨矿。然而，分离伴生矿物(如磷灰石、萤石和方解石)和白钨矿是具有挑战性的，因为它们的表面物理化学性质与白钨矿相似。幸运的是，研究人员在使用抑制剂分离白钨矿矿物方面取得了实质性进展。本文综述了无机抑制剂在含钙矿物制钨中的应用及其抑制机理。综述了新型有机抑制剂在含钙矿物制钨中的应用及其机理。在客观评价了无机和有机抑制剂的优缺点后，提出了无机和有机抑制剂未来可能的研究方向。为白钨矿浮选抑制剂的研制提供了理论依据。
