A review of the beneficiation of rare earth element
The principle separation processes employed in the beneficiation of rare earth minerals include gravity separation, magnetic separation, electrostatic separation and froth flotation These processes will be examined as they have been applied to rare earth mineralsThese minerals may be beneficiated using gravity, magnetic, electrostatic and flotation separation techniques Increased demand for the different products manufactured from REE has resulted in a constriction of supply from China, which currently produces 97% of the world’s rare earths, A review of the beneficiation of rare earth element Prior to individual REE separation, the rare earth ore will go through a series of physical separation and hydrometallurgical processing In this chapter, the rare earth ore beneficiation, mineral concentrate decomposition, and rare earth leaching are introduced brieflyRare Earth Beneficiation and Hydrometallurgical

The beneficiation potential of the three ligands decreases in the order SHA > BHA > SA, as reflected by both sample grade and total rareearth oxide (REO) recovery From an ore sample containing 77% rareearth oxide by weight, flotation with SHA results in the greatest total recovery of REO (666%), with an increase in grade to 334% REO Rare earth elements (REE) are generally considered to be the fifteen elements of the lanthanide series, plus yttrium (which occurs substitutionally with many REE in various minerals), and occasionally scandium The beneficiation of mineral deposits containing economically extractable concentrations of these elements is an area of active researchBeneficiation of the Nechalacho rare earth deposit Rare earth minerals (REM) may be beneficiated using a variety of separation techniques with froth flotation being the most commonly applied in operating REM separation plants Many different collectors have been tested with traditional REM such as bastnäsite The most successful are the hydroxamic acidsBeneficiation of the Nechalacho rare earth deposit
