Rare earth elements and the supply and demand of these resources are increasingly major newsitems. The global mining industry has ramped up exploration for mineral deposits containing rare earth elements to meet the perceived future demand. High prices for rare earth elements continue to drive ...
Rare Earth Elements (REE) are a group of elements that include the lanthanide series of elements, as well as scandium and yttrium. They are used in various industries such as engineering, space, and energy, and are particularly valued for their magnetic properties. REEs are found in over 200...
4.1. Rare earth element composition A brief overview on the rare earth elements characteristics of sub-economic and economic porphyry copper systems is presented below. Here, the chondrite normalizing values are from Evensen et al. (1978) and Eu anomalies were calculated from: Eu/Eu* = Eun /...

Rare earth elements (of which there are 17) occur in ore deposits tightly bonded together and in varying proportions. For example, the deposits in the north have a relatively large proportion of the lower-valued lanthanum and cerium elements. These two products are frequently stockpiled at the ...
He relates the whole history of his observations of Saturn's moon, and gives the elements of its orbit fairly accurately. Since it was he who discovered Saturn's satellite, Huygens argues that his telescopes are better than those of anyone else, and therefore he is justified in sitting in ...
10.2 The rare earth elements The rare earths form a group of 17 elements that have atomic numbers from 57 through to 71, but also include yttrium (Y) and scandium (Sc).53,54 The elements from 57 to 71 are also referred to as the lanthanoids or lanthanide elements after the element ...
Rare earth-based phosphors are termed triband or triphosphorus emitting green [LaPO4:Ce, Tb], red [BaMgAl10O17:Eu & (Sr, Ca, Ba)5(PO4)3Cl:Eu] and blue [Y2O3:Eu] phosphors. They use varying amounts of key rare earth elements basically based on yttrium, europium, and terbium. ...
