Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little ...
Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
Aug 28, 2017 study, the flotation tests on fluorite, quartz and a weight equivalent mixture (all Common depressants used in fluorite flotation are water glass, The Improvement Effect of Dispersant in Fluorite Flotation Hindawi. Aug 26, 2014 Different dispersants were added in the dispersion process to improve the efficiency of fluorite flotation.
Fluorspar / Fluorite Mineral Flotation. Fluorspar (also referred to as fluorite) is a mineral composed of calcium fluoride, CaF 2.It is a naturally occurring mineral that tends to form in rocks that have been subjected to hydrothermal activity.
Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP or H4L) is widely used as an environmentally friendly ...
The development of new collectors to separate fluorite from barite is urgently needed in mineral processing. In this study, the flotation behavior of fluorite and barite was studied using sodium petroleum sulfonate (SPS) as a collector with sodium hexametaphosphate (SHMP) as a depressant.

The beneficiation of fluorite ore is gravity separation and flotation process. The specificity of fluorite flotation: 1. Because industrial making hydrofluoric acid require calcium fluorite content>98% and silica <1%, fluorite flotation generally use 5-7 stages concentration; 2. When the PH of ore pulp is 8-11, the floatability is good. Another, increasing the temperature of ore pulp can ...

In flotation of fluorite, it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite concentrate. Mixed flotation of fluorite and barite flotation, and then separate them. In mixed flotation, obtain …
Regarding fluorite, the flotation recovery of fluorite changed slightly as compared to the result for using NaOl alone. Therefore, the optimum pH to separate fluorite from barite is deemed to be pH 8–9.5 when using TSP as the depressant and NaOl as the collector.
The sulfide ore contained in fluorite (fluorspar) is floated with xanthate collector, and then fatty acid collectors float fluorite (fluorspar). In flotation of fluorite, it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite …

The types and dosage of dispersant on the improvement of fluorite flotation were investigated; when the sodium polyacrylate (SPA) was used as the dispersant and its addition is 0.5%, the concentrate grade of CaF2 increased from 90% to 98% and the fluorite recovery increased from 81% to 85%.
Fluorite is one of common non-metal minerals, which is also called CaF2. Fluorite has rich colors. It is important fluoride minerals for industry. Fluorite common grow with calcite, dolomite, quartz, barite, pyrite, galena, blende and so on. Fluorite has similar characteristics with calcite, barite and other common gangue minerals. It is difficult to separation them […]
