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 general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. ... reverse flotation of the carbonate minerals is a possible ...
Apr 24, 2019· 2.1 Quartz type fluorite ore. The separation of quartz and fluorite achieved by grinding, it is an important factor affecting the flotation of quartz-type fluorite. The ground ore of a coarse size indicates that may have many associated fluorite ore lumps, these lumps may increase the silica content, decrease the flotation effect.
Fluorite Flotation Separation. Fluorite, also known as fluorspar, is a major source of industrial fluoride elements, 20 kinds of the world, one of the important non-metallic mineral raw materials, fluorite is widely used in the metallurgy of aluminum, glass, ceramic, cement chemical industry.
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.
In addition to the calcium fluorite ore dressing process. In addition to a calcium fluorite ore dressing process, there are a variety of working oleic acid or alternatives, sulfuric acid is a mixture of calcium silicate mineral inhibitors, and the proportion of sulfuric acid and acidic water glass is 1:0.5~1:2 The amount of joint is 0.5~1.5kg / t ore.
The article presents experimental research into intensification of fine-disseminated carbonate-fluorite ore flotation by adding FLOTOL-7,9 agent. It is shown that the optimal agent modes allow the yield of the saleable fluorite product of above 90% CaF 2 grade at higher than 60% fluorite extraction.
Fluorite is a widely occurring mineral that occurs globally with significant deposits in over 9,000 areas. It may occur as a vein deposit, especially with metallic minerals, where it often forms a part of the gangue (the surrounding "host-rock" in which valuable minerals occur) and may be associated with galena, sphalerite, barite, quartz, and calcite.
Fluorite mineral processing used fatty acid, oleic acid and xanthate as collector. Fluorite is one kind of mineral with chemical components as calcium fluoride (CaF2), the low melting point, according to its transparency, crystallization condition and use, can be divided into ordinary fluorite and fluorite .
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 ...
Abstract. The authors provide insight into the problem of selective flotation of fluorite from carbonate-fluorite ores. It is found that oxyhydrate collectors used in combination with sodium fluoride provide rather high level of selectivity in fluoride flotation from poor high-carbonate ores and make it possible to eliminate high-temperature pulp treatment with acceptable reduction in the ...
5. ln the froth flotation of fluorite from a calcareous gangue with a fatty acid collector for the fluorite in an aqueous alkaline ore pulp, the improvement which comprises activating said pulp for the selective flotation of fluorite by adding sodium bisulflte in amount within the range of A to 2 lbs/ton.
In view of the disadvantages of depressing calcite and floating fluorite in the traditional fluorite flotation, it may be a promising alternative to remove calcite from fluorite ore in a reverse way, especially for complex and unmanageable fluorite ores containing high-grade calcite gangue mineral [4,12].
Known method of fluorite flotation of carbonate-bearing ores [A.S. USSR №1530261, publ. 23.12.89, BI No. 47], including pre-conditioning of the pulp in an alkaline medium with sodium humates, modified triethanolamine salt lauryl sulphate, as a modifier and fatty acid collector and the allocation of fluorite.

Fluorite ore processing methods which is one roughing repeatedly choice,as a collector agent rougher with oleic acid or its substitute. The process is simple, low-cost advantages can be selected from the high calcium fluorite ore grade fluorite concentrate with a low content of calcium carbonate.
The flotation of fluorite from ores by using acidized water glass (AWG) as depressant has been studied for the substitution of the commonly used depressant (soda ash plus sodium lignosulfonate).
Such is the case of this fluorspar ore which is characterized by the presence of a portion of the fluorite in extremely close association with calcium carbonate and silica and containing appreciable clay. High acid grade fluorspar concentrates are difficult to obtain from this class of ores by flotation with an ordinary .
Flotation separation of carbonate fluorite ore is a puzzle in mineral processing. In this study, the flotation separation of fluorite from calcite using polyaspartate (PASP) as depressant and sodium oleate (NaOL) as collector was investigated, and the adsorption mechanism was analyzed by zeta potential measurement and infrared spectrum (IR) analysis.
Carbonate flotation of this ore at pH 4.5, using sulphuric acid as pH regulator, was carried out with three different collectors—oliec acid, tall oil and OA-5 (a sodium salt of sulphonated oleic acid). The total collector dose used for carbonate flotation, 1.5 kg/t was added in three steps for maximum selectivity in carbonate/phosphate ...
molybdenum and fluorite separately reduce flotation yield [5]. Flotation tests on fluorite ores with various carbonate content (CaCO3 contents from 4.43% to 74.40%) were carried out using acidized sodium silicate as modifier and oleic acid as collector. A high purity fluorite concentrate (99% CaF2) was obtained. It was demonstrated that acidized
Fluorite Flotation Process,Fluorite Flotation Separation, The present invention provides a carbonate - fluorite ore economic effective flotation separation method, especially for the high carbonate content of the flotation separation of fluorite ore The key is to choose the carbonate minerals inhibitors - acidified water glass processing drug measures in the conventional process conditions ...
Improving fluorite flotation from ores by dispersion processing. Shaoxian Song Hu, A. Lopez-Valdivieso, C. Martinez-Martinez, R. Torres-Armenta. Ingeniería minera (SNI 3) Resultado de la investigación: Contribución a una revista › Artículo › Investigación › revisión exhaustiva.
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 (fluorspar) concentrate. Mixed ...
