ANSTO successfully “Close the Gap” on impurity removal and precipitation losses from historic Caldeira MREC testwork on first pass testwork – further optimisation continues. New testwork delivers significantly improved recoveries of key basket elements including:
o 42% increase to Praseodymium (Pr) recoveries upgraded to 74%.
o 14% increase to Neodymium (Nd) recoveries upgraded to 73%.
o 29% increase to Dysprosium (Dy) recoveries upgraded to 50%.
o 12% increase to Terbium (Tb) recoveries upgraded to 53%.

Exceptional Magnet Rare Earth Element (MREE) leach extractions, include;
o 48 different metallurgical composites across ALL deposits had a TREO head grade of >4,000ppm and achieved average Magnetic REE leach extractions of 73% with 74% Nd, 71% Pr, 57% Tb and 56% Dy with a standard AMSUL wash (unoptimised) at pH4.
o 81% magnet metal extractions over 10.4m from CVNDD001 with a high of 88% including 90% for Nd, 86% for Pr, 79% for Tb and 84% for Dy.
o 73% magnet metal extractions over 8.4m from SBDD009 with a high of 75% including 76% for Nd, 73% for Pr, and 63% for Tb & Dy respectively.
o 80% magnet metal extractions over 5.6m from DM2DD001 with a high of 85% including 87% for Nd, 81% for Pr, 73% for Tb and 77% for Dy.
o 73% magnet metal extractions over 8.7m from CDMDD009 with a high of 75% including 77% for Nd, 74% for Pr, 55% Tb and 55% for Dy.
