Gravity separation method is mainly used to extract coarse-grained massive metallurgical grade fluorite ore; gravity beneficiation of fluorite ore is mainly completed by jig concentrator and the material separation effect is remarkable.. 2. Flotation separation is mainly used to produce high-quality fluorite concentrate. The main problem of fluorite …
In this study, to enhance the flotation of fine-grained fluorite, a strategy that combines simultaneous grinding and surface modification via ball-milling and controlled …
At present, the primary beneficiation approach of fluorite is flotation [5].In the deposits, fluorite is often associated with gangue minerals such as calcite and quartz, which share similar surface properties with fluorite (i.e. solubility, crystal structure, hydrophobicity, and zeta potential), making the effective separation challenging to …
In this review, analyses of the fundamental reasons for the difficulties of flotation separation of fluorite from calcite are performed, from the similar surface …
When the raw ore is coarse-grained fluorite ore, a gravity separation process can be used. The flotation process can be used when the raw ore has a high mud content, is accompanied by impurity ...
Hence, the development of a highly efficient reagent for fluorite holds paramount significance and value in addressing the challenging separation of fluorite and calcium-bearing minerals. In this study, a novel collector, decyl-bishydroxamic acid (DCBHA), has been ingeniously designed and synthesized to effectively separate …
By carefully adjusting parameters such as feed rate and water flow, effective separation of scheelite and fluorite can be achieved, paving the way for high-quality concentrates of each mineral. When …
