What minerals are found with apatite?

Apatite is a phosphate mineral (and is the most abundant phosphorous-bearing mineral). The name actually covers three different minerals (fluorapatite, chlorapatite and hydroxylapatite) depending on the predominance of either fluorine, chlorine or the hydroxyl group.

Is apatite a rock or mineral?

Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. They are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals.

Is apatite a primary or secondary mineral?

Apatite is a common mineral, and often a secondary mineral ingredient in almost all igneous rocks, especially in pegmatite and mafic igneous rocks forming as veins. The primary use of apatite is in the manufacture of fertilizer and a source of phosphorus.

Where is apatite mineral found?

Apatite is found in Myanmar (Burma), Brazil, India, Kenya, Madagascar, Norway, Sri Lanka, South Africa, Mexico, Canada and the United States. There are three minerals that actually contribute to apatite, which is the reason for the varied colors and shades of this stone.

What is apetite mineral?

Apatite refers to a group of phosphate minerals which includes fluorapatite, chlorapatite, hydroxylapatite, carbonate-rich apatite, and francolite, the most common of which is fluorapatite. The word apatite is derived from the Greek word for deceit, “apate” because apatite can be mistaken for many other minerals.

Is coal a mineral?

While coal is naturally occurring, it is organic and thus does not meet the ASTM’s definition of “mineral”.

How is apatite formed?

Apatite forms under a wide variety of conditions and is found in igneous, metamorphic, and sedimentary rocks. The most important deposits of apatite are in sedimentary rocks formed in marine and lacustrine environments. There, phosphatic organic debris had accumulated and was mineralized during diagenesis.

What is the value of apatite?

Apatite Price Apatite usually sells for ₹ 500 to ₹ 20,000 per carat and above.

What is apatite mineral used for?

Uses of Apatite as Phosphate Rock Most of the phosphate 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.

What are the types of apatite?

The primary Apatite group includes Fluorapatite, Chlorapatite, and Hydroxylapatite. The extended Apatite supergroup describes additional minerals such as Pyromorphite, Mimetite, and Vanadinite, but these are described individually in this guide.

What minerals are in coal?

The most common minerals in coal (for example, illite clay, pyrite, quartz, and calcite) are made up of these most common elements (in rough order of decreasing abundance): oxygen, aluminum, silicon, iron, sulfur, and calcium.

What type of mineral is coal?

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.

What is the mineral apatite used for?

Is apatite expensive?

High quality apatite gemstones can rival the beauty of other more valuable gemstones and when set in well-crafted jewelry, apatite really stands out. Due to its affordability and easy availability, this is a gemstone that anyone can afford.

What is the hardness of apatite?

hardness 5
If not for its softness (Mohs hardness 5, compared with the 7 to 9 of most gems), apatite would be a popular gemstone; much of the material found is clear, but it is fragile and difficult to cut and polish.

What is composition of coal?

Coal is mostly made up of carbon, with varying proportions of additional elements such as hydrogen, sulphur, oxygen, and nitrogen. Coal is generated when dead plant matter decays into peat, which is then transformed to coal over millions of years by the heat and pressure of deep burial.

Is coal a rock or mineral?

Coal is a black sedimentary rock that can be burned for fuel and used to generate electricity. Coal is the leading source of energy in the United States. Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.
