May 14, 2018· Typical processing involves mining the ore and beneficiating through sizing and flotation to produce a "phosphate rock" concentrate containing over 29 pct P2O5. This concentrate is ground to 90 pct minus 75 µm and leached to dissolve the phosphate. Apatite, Ca5(PO4)3(F, Cl, ½CO3, OH), is the primary phosphate mineral in the phosphate rock.
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. Green and blue apatite are ground and used as pigments with excellent covering power.
The mining process of phosphate ore deposits includes prospecting, exploration, mine development and ore exploitation. The ore extraction could be underground or open pit which is the most common method. The main phosphate rock extraction stages in open pit are drilling, blasting, excavating, loading, haulage and dumping.

Mar 04, 2019· How quartz is processed. Quartz forms when silicon and oxygen combine in the earth. It is found in massive form in late-melt igneous deposits such as pegmatites and often occurs with other materials such as spodumene (a lithium ore), feldspars, garnet and micas. As quartz is one of the major constituents of continental rocks, it is found in ...

Aug 09, 2021· Uranium Ore (Carnotite). Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining.The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.
Blue Apatite Properties. Blue apatite is a form of the mineral group that was named apatite in 1786, although the strict definition of this mineral formation was not determined, as it is used today, until 1860. The mineral apatite comes from a Greek word meaning "to deceive," because of its unusual origins.
Apatite is found in a wide variety of rock types. Igneous rocks are usually characterized by F and OH varieties, some containing Mn. Apatite occurs in pegmatites, hydrothermal veins and cavities, metamorphic rocks, and as detrital grains in sedimentary rocks and phosphate beds. Healed fractures, hollow growth tubes.

Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. (These biological Apatites are almost exclusively the Hydroxylapatite type.) Chemical Formula.
Mining: Apatite is most often mined in massive bedded marine deposits which are mined for phosphorus to be used in fertilizers.
