Eng Free Full-Text Recovery of Rare Earth Elements Minerals

The rapid depletion of high-grade rare earth elements (REE) resources implies that future supplies may be augmented with low-grade ores, tailings, and other unconventional resources to meet cut-off grades and, subsequently, supply demands. This paper presents an amalgamation of studies conducted on selected complex low-grade iron-oxide-silicate In the metallurgical extraction of rare earth elements (REEs), the ratio of contaminant ions to REEs in the leachate dictates the cost and operational efficiency of the downstream processes.

Gravity Separation an overview ScienceDirect Topics

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.The theoretical heat required by the furnace is about 0.94–1.21 GJ/tonne of RE contained in bastnäsite whereas the energy use in real processes is 1.44–2.16 GJ/tonne RE chlorides. 9 Thus, to obtain 1 tonne of REE from bastnäsite in Mountain Pass, between 4.26 GJ and 6.32 GJ are needed.Material and Energy Requirement for Rare Earth Production
