低品位白钨矿选矿技术的研究发展

Research Development of Low-grade Processing Technology for Scheelite

系统地介绍我国低品位白钨矿选矿技术现状及发展。详细阐述了浮选、非浮选选矿工艺以及选矿联合工艺在低品位白钨矿的选矿中的作用及其进展。重点指出对于品位低、组分复杂、细粒嵌布的白钨矿,单一选矿工艺已经很难解决问题,加大力度研究重、磁、浮、化等选矿工艺之间联系,组成联合工艺,实现各个工艺之间的优劣势互相补充,协同效应最大化,是未来大力度开发利用低品位白钨矿,保持我国钨业持续发展的发展方向。

The status quo of Chinese low-grade scheelite processing technology and its development is introduced systematically. The function and research development of flotation, non-flotation and the combined technology for the low-grade scheelite are set forth. It emphasizes that for the low-grade, complicated constituents, fine-disseminated scheelite, single beneficiation process has been unable to solve it. Further research on the combination of gravity separation, magnetic separation ,flotation, and chemistry separation must be carried to realize the complementary of the advantages and disadvantages of various processes, maximizing the synergistic effect. It is the development direc- tion of utilization of scheelite and sustainable development of Chinese tungsten industry.
