A review of the beneficiation of rare earth element

Feb 01, 2013 The availability of HREE is even further impacted by the fact that the rare earth element distributions of the two most commonly extracted rare earth minerals, bastnäsite and monazite, exhibit lower percentages of the elements samarium to lutetium than would be expected based on the abundance data from Fig. 2 (Gupta and Krishnamurthy, 1992).

Monazite Wikipedia

Monazite is a reddish-brown phosphate mineral that contains rare-earth elements.Due to variability in composition, monazite is considered a group of minerals. The most common species of the group is monazite-(Ce), that is, the cerium-dominant member of the group. It occurs usually in small isolated crystals.It has a hardness of 5.0 to 5.5 on the Mohs scale of mineral hardness and is relatively

1963). The crustal abundance of the individual rare earth elements is shown in Fig. 2. As a comparison, the crustal abundance of gold and silver are 5 10 7 wt.% and 1 the year 2015 (10 5 wt.% respectively (Trifonov, 1963). The difficulty in rare earth mineral exploitation is that the rare earth minerals are not commonly found in eco-

Rare-earth element Wikipedia

The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and
