Brazilian Rare Earths Achieves Exceptional Ore Sorting Results at Monte Alto

Core Insights - Brazilian Rare Earths Limited (BRE) has reported exceptional results from its sensor-based ore sorting test program, confirming its suitability for the Monte Alto beneficiation process flowsheet [1][2] Company Highlights - The ore sorting results have exceeded expectations, demonstrating that sensor-based concentration can enhance project economics with yields exceeding 95% at lower capital and operating costs, while also reducing environmental impact through lower energy use, minimal water, and no reagents [3][4] - The metallurgical programs aim to maximize the value of Monte Alto's ultra-high grade rare earth, uranium, scandium, niobium, and tantalum mineralization, building on previous programs with the Australian Nuclear Science and Technology Organisation (ANSTO) [4][5] - The multi-sensor ore sorter enriched the run-of-mine Monte Alto feedstock by over two times in a single pass, producing a concentrate of over 27% Total Rare Earth Oxides (TREO) [6][8] Industry Context - Rare earth projects typically face challenges with low head grades and complex, high-cost processing flowsheets; however, Monte Alto's ultra-high grades allow for a beneficiated product suitable for direct hydrometallurgical processing [7] - The company plans to progress flowsheet design targeting a multi-sensor system capable of processing 100% of Monte Alto's run-of-mine material with yields exceeding 95% [7][8] - The results validate the potential for downstream direct rare earth extraction, highlighting lower capital and operating costs, and enhanced project economics [8]
