The development of tungsten flotation technology has been significantly influenced by the evolution of flotation reagents, transitioning through various stages such as fatty acid flotation, chelating agent flotation, and metal–organic complex flotation. This chapter summarizes the progress and application of tungsten flotation technology, with a focus on the three main flotation technologies: fatty acid flotation, chelating collector flotation, and metal–organic complex flotation. The fatty acid method, which includes both normal temperature flotation and “Petrov” heating flotation, is widely used due to its strong collecting ability and adaptability to ore properties. Chelating agent flotation, primarily using hydroxamic acid, cupferron chelating agents, has been extensively applied in the flotation of wolframite and mixed ores of scheelite and wolframite. The metal–organic complex flotation method, utilizing a highly selective collector, has emerged as a novel technology capable of achieving normal temperature separation of complex tungsten resources, offering a new solution for efficient flotation separation of complex tungsten ores. The chapter also discusses the application of these technologies in various tungsten mines, highlighting the advantages and challenges associated with each method. The fatty acid method, despite its adaptability and low reagent cost, has a complex process and high energy consumption. The chelating agent method can achieve high-grade concentrates but requires heating and has high reagent costs. The metal–organic complex method simplifies the process and improves tungsten recovery, offering a promising direction for the future of tungsten flotation technology.
