REE MARKET MAIN PROBLEM
Y La Ce Pr Nd Sm Eu Gd Tb Dy Ho Er Tm Yb Lu Sc
Conventional production technologies
require processing of 100% ore to
produce most precious 5-10% REEs;
Key problem is low selectivity
technological restrictions of existing
methods (enrichment/
sorption/extraction);
1/3 of REEs produced are sold below
cost.
