Monazite: A rare-earth phosphate mineral.
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 ...

Rare earth elements in sedimentary phosphate deposits ...
The critical role of rare earth elements (REEs), particularly heavy REEs (HREEs), in high-tech industries has created a surge in demand that is quickly outstripping known global supply and has triggered a worldwide scramble to discover new sources. The chemical analysis of 23 sedimentary phosphate deposits (phosphorites) in the United States demonstrates that they

Rare Earth Elements From Phosphate Waste
2019-3-11 Rare earth elements typically are found in concentrations less than 0.1 percent in phosphate rock. That means about 100,000 tons of these elements per year end up in phosphogypsum waste—almost as much as the approximately 126,000 tons of rare earth oxides produced worldwide each year. Recovery

2018-9-19 Phosphorite, or phosphate rock, is the raw material of phosphoric acid production. It has also been regarded as the most important secondary rare earth element (REE) resource due to low contents of rare earth elements contained in the ore. In Florida, there is about 19 Mt of phosphate rock mined annually. After beneficiation, the phosphate rock concentrate is utilized
