Resources Pit Design Metallurgy Beneficiation – Ore Sorting Ore sorting is the proposed technology to produce a bastnaesite concentrate from the North T ore body. Ore sorting involves the separation of the bastnaesite mineralisation from the quartz gangue using XRay Transmission (XRT) technology. This sensor was deemed suitable due to the significant .

· A new process suggested for the selective dissolution of rare earth elements REEs from xenotime concentrate produced after physical beneficiation namely; shaking table and froth flotation were proposed using ammonium sulfate. The suggested procedure was established upon the selectivity of ammonium sulfate as a leaching agent of rare earth element.

7% of the total rareearth minerals are disseminated in the ironoxide minerals. The deposit contains bastnaesite and monazite with magnetite and hematite as the dominant iron minerals. This ore is beneficiated into a 65% REO concentrate with an overall rareearth recovery of about 61% via a complex beneficiation process.

The mineral concentrate of was then leached at the Outotec Pori Research Laboratories, Finland producing ~25 kilograms of mixed rare earth carbonate with 50% REO content.. This was then processed by MEAB Chemie Technik GmbH, Aachen to produce separate streams of La/Ce, Nd/Pr, Y and HREE chloride fractions.
Two Ecoinvent unit processes,, rareearth concentrate, 70% REO, from bastnasite, at beneficiation/CN and neodymium oxide, at plant/CN were split into five processes: ore removal from mine, beneficiation of REE containing ore, acid roasting, leaching, and solvent extraction.

Rare earth production at Mountain Pass. The Mountain Pass mine was estimated to produce 26,000 tonnes (t) of rare earth concentrates in 2019 compared to 18,000t in 2018. The USA's sole operating rareearth mine accounts for more than 10% of the world's total rare earth concentrates production.
