Rare Earth Elements From Phosphate Waste . Mar 11 2019 · Rare earth elements typically are found in concentrations less than 01 percent in phosphate rock That means about 100000 tons of these elements per year end up in phosphogypsum wastealmost as much as the approximately 126000 tons of . .
In some lowgrade phosphate rock mines, the content of Fe and Al is even higher than that of P2O5, and it is usual that the P2O5 content in phosphate rock is less than the Si and Ca content. In addition, some elements that are very rare in the Earth's crust are found to be relatively abundant (Fig. 1) in phosphate rocks [17]. ...
· Both phosphate rock and rareearth metals are classified as strategic raw materials in the EU. The risks to the security of supply of rareearth metals, which are used extensively in green technologies, are very high because their biggest supplier on the global market is China. The director of the Geological Survey of Estonia, Sirli Sipp Kull, said the size of the market for rareearth metals ...

· Extracting Rare Earth Elements from phosphate deposits in the United States. The Rare Earth Elements (Lanthanum, Cerium, Prasedymium, Neodymium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium, Lutetium and Yttrium) are of vital importance in many modern hightec industries. Unfortunately, as their name suggests they are extremely rare.
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 grains are resistant to weathering and become concentrated in soils and sediments downslope from the host rock.
