Another step in the right direction,,,,

74.5% of the total REEs and >75% of magnet REE’s (Nd + Pr) can be concentrated in the fine fraction, which makes up just over half (51%) of the sample volume. • A reduction of nearly half of the feed volume of REE bearing clay material would significantly lower acid consumption and would mean a substantial reduction in both the OPEX and CAPEX at REE extraction stage. • Concentration of REE’s in half the volume of material can be achieved by simple screening and recovering the -20 µm fraction. • This is the fraction that also contains the potentially valuable kaolin by-product.
