Brazilian Rare Earths Limited (ASX: BRE / OTCQX: BRELY) reports exceptional results from ore sorting test work at Monte Alto. Achieved grade upgrade factors of >2x, increasing feed grades from 12.4% TREO to ~27% TREO. High-grade product produced in single-pass processing with world-class recoveries of 95% and efficient waste rejection of ~25%.
The ore sorting results exceeded expectations, enhancing project economics with +95% yields at lower costs. The metallurgical programs aim to maximize the value of Monte Alto’s ultra-high grade rare earth minerals. Previous programs with ANSTO demonstrated direct hydrometallurgical processing, including impurity removal and uranium recovery.
The multi-sensor ore sorter enriched Monte Alto feedstock by over two times in a single pass, producing a concentrate of +27% TREO. Subsequent runs produced a +20% TREO concentrate at very high total recoveries of 96-99%. BRE will progress flowsheet design for processing 100% of Monte Alto’s material at +95% yields.
Bernardo Da Veiga, Managing Director and CEO, emphasized the significant economic and environmental benefits of the ore sorting results. The company aims to target a multi-sensor system for processing Monte Alto’s material, offering high-grade product yields suitable for direct hydrometallurgical processing.
