Apatite Mineral Processing

Apatite - Wikipedia

Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and stone mineral. A relatively rare form of apatite in which most of the OH groups are absent and containing many carbonate and acid phosphate substitutions is a large component of stone material.

Apatite: The mineral apatite information and pictures

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.

Apatite - Mineral and Healing Properties

Apatite is one of a few minerals produced and used by biological micro-environmental systems. Apatite is also a prized mineral specimen by collectors. Origin Of The Name. The name Apatite is derived from a Greek word meaning "to deceive" because the variety of colors and formations in which this stone occurs makes it easy to mistake for other ...

Apatite: Mineral information, data and localities.

"Apatite" is a field term for unidentified calcium phosphate members of the apatite group. Most "apatite" is fluorapatite, whereas hydroxylapatite is much less common and chlorapatite is very rare. "Apatite" crystals are short to long hexagonal prisms [0001], with {10 1 0} and {10 1 1} dominant; also thick tabular {0001}, frequently in the crystals of hydrothermal origin in pegmatites and ...

Fluorapatite - Wikipedia

Fluorapatite, often with the alternate spelling of fluoroapatite, is a phosphate mineral with the formula Ca 5 (PO 4) 3 F (calcium fluorophosphate). Fluorapatite is a hard crystalline solid. Although samples can have various color (green, brown, blue, yellow, violet, or colorless), the pure mineral is colorless as expected for a material lacking transition metals.

Acid Alcohol Leaching of Apatite

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.

Apatite Gemstone Information - GemSelect

Apatite is a very common mineral, but transparent gemstone-quality apatite is extremely rare. Despite the fact that apatite is the defining mineral for 5 on Mohs scale of hardness, the gemstone remains virtually unknown to most, and is seldom found in jewelry stores.

Mineral Processing and Extractive Metallurgy Review

ABSTRACTApatite (Ca10(PO4)6F2) is the most important phosphate mineral, and flotation is the main beneficiation method to separate apatite from its major gangue mineral calcite (CaCO3). Till date, ...

Effect and mechanism of phosphoric acid in the apatite ...

Oct 10, 2017 · To elucidate how phosphoric acid (H 3 PO 4) as a depressant achieves selective separation of apatite and dolomite, the flotation response of these minerals was investigated using both single and mixed mineral flotation.Microflotation results demonstrated that H 3 PO 4 exhibits a selective depressive effect on apatite. Flotation kinetics analyses also revealed that the presence of H 3 PO 4 ...

Mineral processing wastes are available from mining and mineral processing operations, most of which are located near the mine source and operated by mining companies. The quality of mineral processing wastes can vary widely and is highly dependent on the specific source.

Green Apatite - Meanings

The distribution volume of Green Apatite is small. You will find it in a gemstone shop that is strong in rare stones. General gemstone shops seldom sell it. Green Apatite which combines "high transparency" and "beautiful coloring" becomes more expensive. When processing high quality stone into accessories, it becomes outstandingly beautiful.

Titanite Ores of the Khibiny Apatite-Nepheline-Deposits ...

Geological setting and mineral composition of (apatite)-nepheline-titanite ore from the Khibiny massif enable selective mining of titanite ore, and its processing with sulfuric-acid method, without preliminary concentration in flotation cells. In this process flow diagram, titanite losses are reduced by an order of magnitude in comparison with a conventional flotation technology.

Apatite Group: Mineral information, data and localities.

The group has its name after the generic name apatite first introduced by the German mineralogist Abraham Gottlob Werner in 1786 (Gerards 1786). It is derived from the Greek ἀπατάω (apatao), to deceive, in allusion to apatite often being confused with other minerals (e.g., beryl, milarite).
