Only jig can deal with the coarse fluorite ore. Fluorite flotation equipment includes crusher, ball mill, flotation machine etc. Jaw crusher is the primary crusher. It is used in fluorite coarse crushing process. Cone crusher is the fine crushing machine used in fluorite processing plant. After fluorite crushing process, fluorite is less than 15mm.
The surface characteristics of fluorite and calcite exhibit a close analogy, posing a formidable challenge to flotation separation. 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.
1. Introduction. Scheelite (CaWO 4) often coexists with calcium-bearing gangue minerals like fluorite (CaF 2) and calcite (CaCO 3).Due to the similar surface physicochemical properties, it is difficult to separate scheelite from calcium-bearing gangue minerals by flotation efficiently [1], [2], [3].Petrov process (PP) offers a viable solution …

Fluorine is commonly utilized as an industrial additive in aerospace, separation of uranium-235, semiconductors, medicine and other areas of national importance [1].The primary source of elemental fluorine is fluorite (CaF 2), recognized as a strategic mineral resource by several countries [2].Typically, fluorite separation is …
The flotation of the precipitates after seeding crystallization precipitant can recover 83.14% of CaF 2 with a grade of 64.42%, and the products can be used to replace parts of metallurgical-grade fluorite. As a result, the fluorine in the wastewater changed into useful products.
The recovery of fluorite decreased more rapidly than barite when the SHMP concentration was increased to 2.29 × 10 −6 M and the difference in recovery was about 60%. With a further increase in the SHMP dosage, the difference in recovery between fluorite and barite reduced. 3.3. Flotation of artificial mixed minerals

With the rapid development of new energy industry, the importance of fluorine chemical industry gradually appears (Asadi et al., 2018).As the dominant raw material for extraction of fluorine, the demand of fluorite also increases rapidly (Liu et al., 2019b, Miller et al., 1989).Froth flotation has been widely applied to separate and enrich fluorite …
The floatability of fluorite and calcite as a function of NaOl dosage at pH 8.0 is shown in Fig. 4.As seen in Fig. 4, flotation recoveries of fluorite and calcite significantly increased with increasing dosage of NaOl and remained constant at high collector concentration.The flotation recovery of both fluorite and calcite was over 90 % using …
It has been well appreciated that the froth flotation is of the most importance. However, to the best of the authors' knowledge, it lacks a thorough and critical review on the recent …
In general, forth flotation is the most effective method to separate barite and fluorite [8].Fatty acids and alkyl sulfonic acids are common flotation collectors [9].However, the collector can be adsorbed on the mineral surface through the coordination of –COO-and −SO 3-with Ca and Ba site [10], [11].The separation of barite and fluorite is very unlikely …
