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.

Acid Alcohol Leaching of Apatite

Apatite, Ca5(PO4)3(F, Cl, ½CO3, OH), is the primary phosphate mineral in the phosphate rock. During leaching the apatite is solubilized as H3PO4 and the calcium content of the apatite is precipitated as calcium sulfate. In addition, any impurities in the ore are usually solubilized; the most common impurities are iron, aluminum, and magnesium.

Blue Apatite Meanings and Uses | Crystal Vaults

Blue Apatite Goddess Crystals. Blue Apatite honors Gaia, the Greek Earth Mother Goddess. Born directly out of Chaos, the primal emptiness, she was the first (or one of the first) beings to appear during the process of creation, and is honored as being the Earth itself.

Apatite - an overview | ScienceDirect Topics

Apatite (Ca 10 (PO 4) 6 (OH,F,Cl) 2) is the most common mineral for phosphates production, particularly for fertilizers and phosphoric acid.Apatite can be igneous or sedimentary. Almost all apatite ores contain rare earth elements, but igneous apatite has a higher concentration than sedimentary apatite.

Apatite Leaching using H2SO4 & Methanol

Since apatite is the dominant phosphate-containing mineral in the waste materials, a study was conducted using research-grade apatite, devoid of any ancillary clays and minerals. Using the crystalline apatite in the acid-alcohol leaching tests provided evidence as to why the extractions are incomplete.

gressively mineralized by poorly crystalline carbonated apatite. The process that precedes mineral’s eventual propagation on the extracellular matrix (ECM), however, remains largely unexplained and is highly controversial. Investigators have proposed various mechanisms to explain early stone mineral formation including:

Jan 28, 2017 · Introduction. Historically, renal calculi associated with urinary tract infection have been identified by the presence of struvite (magnesium ammonium phosphate) in the mineral composition of the stone [1,2, 3].This identification reflects the generally accepted relationship between the formation process of struvite stones and urea-splitting bacteria.

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.

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 ...

How is apatite mined? | Yahoo Answers

Dec 21, 2011 · Phosphate rock consists of the mineral apatite, an impure tricalcium phosphate, mixed with clay and other elements. In 2000, nine companies operated seventeen phosphate rock mines in the U.S. Florida is the main source of phosphate rock in the U.S. It supplies 25 percent of the world and 75 percent of the U.S. demand for phosphate.

A mineralogical perspective on the apatite in bone

by the formation process of the crystalline solid apatite and not merely by the flow and availability of individual elements such as calcium. For instance, in order for the mineral apatite to form, all necessary elements need to be available in the proper proportions, i.e., not only calcium, but also phosphorus, oxygen, and the appropriate channel-

Furthermore, apatite is a biologically important mineral, which has been associated with many life forms from oral bacteria and a few invertebrates, to bone, cartilage, enamel and dentin of human beings (Omelon and Grynpas, 2008). In particular, it provides the mechanical strength of both stone and enamel.
