2019-8-28 Apatite is the main mineral concentrator of phosphorus in the ore; it forms disseminated prismatic crystals, vein clusters of crystals, less often massive clusters of fractured xenomorphic grains, often included in the grains of other minerals - pyroxenes, mica, sphene, nepheline (Fig. 1).

2020-9-1 In the apatite flotation process, carbonate minerals especially magnesium-bearing dolomite are easy to enter into apatite concentrates, reducing the quality of concentrate products and causing excessive acid consumption in downstream processing.

2020-10-13 The major styles of apatite mineralization are veins or veinlets, small pods or patches, disseminated apatite, and massive aggregates (locally). The concentration of apatite involves grinding of the carbonatite, removal of magnetite with a magnet drum, size classification with cyclones, and flotation to suppress carbonates and collect apatite.

Blue apatite is a prized mineral specimen by rock collectors for its vibrant royal blue color. Most of the apatite rock mined throughout the world is used to produce phosphate fertilizer. It is also used to produce animal feed supplements, phosphoric acid, elemental phosphorous, and phosphate compounds for the chemical industry.

2019-8-28 Abstract. The article studies the mineralogical features of phosphate ores. In the conditions of declining industrial reserves of apatite-containing ores, issues of a more comprehensive and in-depth study of the mineral and material composition, as well as the improvement of existing technologies for the processing of this type of raw material, become topical.

2004-2-4 Difficulties are often encountered in processing heterogeneous mineral systems under conditions predicted on the basis of single mineral tests. In systems containing minerals such as calcite and apatite which dissolve to a significant extent in water, the effect of dissolved species on the behavior of these minerals can be severe.

important lithium ore mineral. A typical run of mine ore can contain 1-2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). Higher grade concentrates with 7.6% Li 2 O and low iron content are used in ceramics and more demanding industries.
