Which Minerals Include Phosphate? - ThoughtCo

Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F. Other members of the apatite group have chlorine or hydroxyl that take the place of the fluorine; silicon, arsenic or vanadium replace the phosphorus (and carbonate replace the phosphate group); and strontium, lead, and other elements substitute for the ...

What if we ran out of minerals? | HowStuffWorks

Minerals make up most of what we use to build, manufacture and stand on — including rocks and soil — so if we really ran out of minerals, we'd all be scrambling for a spot on the planet's shrunken surface areas.. But if you were worried about running out of a single mineral important for industry, then you probably can breathe easy. Most of the minerals we use a lot are very abundant.

Calcium Phosphate Mineral - an overview | ScienceDirect Topics

The phosphate ion is commonly associated with other ions, for example, with H +, Mg 2+, and Ca 2+ in aqueous complexes, with Ca 2+ and F − in calcium–phosphate minerals such as carbonatefluorapatite (CFA), hydroxyapatite and fluorapatite and with Fe 2+ and Fe 3+ in Fe-phosphate minerals.

Mineral Resource of the Month: Phosphate Rock | EARTH Magazine

As a mineral resource, "phosphate rock" is defined as unprocessed ore and processed concentrates that contain some form of apatite, a group of calcium phosphate minerals that is the primary source for phosphorus in phosphate fertilizers, which are vital to agriculture.

Mineral Resource of the Month: Phosphate | EARTH Magazine

Phosphate rock refers to unprocessed ore and beneficiated concentrates that contain some form of apatite, a group of calcium phosphate minerals. Apatite in phosphate rock is the primary source for phosphorus in phosphate fertilizers. More than 80 percent of the world's current production of phosphate rock is mined from sedimentary deposits, which were formed by the deposition of phosphate ...

Monazite - Wikipedia

What is Monazite? Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th)(PO 4,SiO 4).It usually occurs in small isolated grains, as an accessory mineral in igneous and metamorphic rocks such as granite, pegmatite, schist, and gneiss.These grains are resistant to weathering and become concentrated in soils and sediments downslope from the host rock.

A carbonate-rich lake solution to the phosphate problem of ...

Jan 14, 2020· Phosphate is crucial for the origin of life because it is ubiquitous in key biomolecules. A major issue is that prebiotic syntheses use concentrated phosphate to incorporate phosphate into biomolecules, whereas natural waters are generally phosphate-poor because phosphate reacts with calcium to form low-solubility apatite minerals. Here we show that carbonate-rich lakes can …
