Without the direct use of fluorite beneficiation are rare in nature. Depending on the user's requirements and the nature of the ore, to use different processing methods, such as metallurgical grade fluorspar general election with a broken screen break method, acid grade fluorspar and ceramic grade powder often flotation, to obtain high-quality ore .
Non-metallic mineral fluorite is one of the minerals easy to float, you can use the fatty acids flotation collectors. Fluorite and often symbiotic minerals are quartz, calcite, barite and some sulphide minerals, such as galena, pyrite. Thus, inhibition of associated minerals is very important.
Fluorite flotation collectors are commonly used in oleic acid, a suitable pH value of 8-10, due to limited sources of oleic about in recent years, commonly used oleic acid substitutes, such as petroleum sulfonate, was also very effective. improve pulp temperature can be significantly improved flotation. Flotation water available zeolite and soda softening.
Of sulfur-containing mineral fluorite ore, usually first with xanthate collector floating sulfide mineral fluorite surfaced again with a fatty acid. Sometimes adding fluorite flotation cycle less sleep cyanide, residual inhibition of sulfide minerals, in order to ensure the quality of concentrate.
There is a small amount of aluminum fluorite activation, dextrin can inhibit the activation of barite and fluorite and calcite, a small amount of sodium silicate at first glance has a similar use. Tannins and gum copy inhibit calcite and barite.
In summary, the following condition is preferably fluorite flotation: warm water flotation, preferably 60-80 ºC temperature; demineralized water; pulp pH value of about 9.5; selection of the least number of 3 or more; adjusting agents may be sodium hydroxide, sodium carbonate, inhibitors white gum shield, Barr Kdan (palcatan, acid derivatives), dextrin, collector available oleic acid, tall oil, petroleum sulfonate.
Separation of fluorite and calcite both in theory or in fact belong to one of the trapped Soviet problem has been proposed, while adding water glass and aluminum, can improve the selectivity of the flotation process, and in the case of obtaining a high recovery rate, availability and grade 95 (CaF2) above concentrate Soviet Allah Colmar fluorite ore dressing plant in Gdansk, with caustic soda, sodium silicate, aluminum salts, oleic acid, pine oil, dextrin and other agents for the flotation, the effect is very good . In addition, the particle size of fluorite have a significant impact on the flotation.
When a large site containing low or even coarse ore grade student body is often used when the re-election of a flotation sorting process.
Fluorite optical methods can also be used for sorting, sorting principle in its liquid and fluorite have equal refractive index, as put in pure fluorite crystal, the naked eye can not recognize. In contrast, as the discharge of crystals containing impurities due to the absorption part of the light of the results, the photovoltaic by camera shadows, this shadow by the photo into a current, after amplification in the circuit, driving the discharge valve photovoltaic concentrator you can discharge impure crystals.
Optical sorting machine consists of the following components: full optical test solution sorting groove; and the whereabouts of mine pulled way at right angles to the incident light; photocell and power amplification device; sorting ore shoots within the dispensing valve or pull block board: room and product delivery systems.
Ore mineral particles of uniform size, according to a rate of about 1.5s, using vacuum suction from the mine will make cross-level lighting, and landed neatly in the twist of the liquid off. Depending on the extent of absorption of light, shadows on the formation of optical imaging machine is different, thus amplifying the current generated in the photoelectric cell is different, resulting in different purity of mine pulled discharged from different discharge mine gate, this method due to the small production capacity , so its application is subject to certain restrictions.
