Rare Earth Minerals In Phosphate Rock

  • Tailings of Florida Phosphate Rock mdpi

    Abstract 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 rockPhosphate minerals , Revolvy,Dyrnaesite-(La) is a recently described rare-earth phosphate mineral with the formula NaCe4+(La,REE)(PO). Dyrnaesite-(La) is related to vitusite-(Ce), another rare-earth phosphate mineral.[1][2] It comes from lujavrite, a type of alkaline syenite rock, of South Greenland.

There are four main varieties of monazite monazite-Ce, monazite-La, monazite-Nd and monazite-Sm. Monazite may also contain thorium making it radioactive. Monazite occurs as a rather rare accessory mineral in certain granitic rocks and pegmatite veins.
