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).

Fluorite primarily occurs as a porefilling mineral in carbonate rocks (limestones and dolostones), as low temperature hydrothermal vein deposits associated with lead and silver ores, and less often as an accessory mineral in pegmatites and granites. It is sometimes even precipitated at hot springs.
Known method of fluorite flotation of carbonatebearing ores [ USSR №, publ., BI No. 47], including preconditioning 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.
Apr 24, 2019· Quartz type fluorite ore. The separation of quartz and fluorite achieved by grinding, it is an important factor affecting the flotation of quartztype 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.
molybdenum and fluorite separately reduce flotation yield [5]. Flotation tests on fluorite ores with various carbonate content (CaCO3 contents from % to %) 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 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 ...
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 57 stages concentration; 2. When the PH of ore pulp is 811, the floatability is good. Another, increasing the temperature of ore pulp can ...
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 nonmetallic mineral raw materials, fluorite is widely used in the metallurgy of aluminum, glass, ceramic, cement chemical industry.
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 highgrade calcite gangue mineral [4,12].
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 .
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 "hostrock" in which valuable minerals occur) and may be associated with galena, sphalerite, barite, quartz, and calcite.
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 ...

Abstract. The authors provide insight into the problem of selective flotation of fluorite from carbonatefluorite ores. It is found that oxyhydrate collectors used in combination with sodium fluoride provide rather high level of selectivity in fluoride flotation from poor highcarbonate ores and make it possible to eliminate hightemperature pulp treatment with acceptable reduction in the ...
Fluorite flotation process . 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 7 stages concentration; 2.

Fluorspar / Fluorite Mineral Flotation. Fluorspar (also referred to as fluorite) is a mineral composed of calcium fluoride, CaF 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:~1:2 The amount of joint is ~ / t ore.

Carbonate flotation of this ore at pH, using sulphuric acid as pH regulator, was carried out with three different collectors—oliec acid, tall oil and OA5 (a sodium salt of sulphonated oleic acid). The total collector dose used for carbonate flotation, kg/t was added in three steps for maximum selectivity in carbonate/phosphate ...
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 .
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 ...
