  • Rare Earth Elements From Phosphate Waste | designnews

    Mar 11, 2019· 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.

  • Monazite: A rare-earth phosphate mineral.

    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.

    Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of carbonate and phosphate minerals, respectively. Carbonatites, and especially phoscorites, are relatively uncommon, as there are only 527 known carbonatites in the world (Woolley and Kjarsgaard, 2008).
