NEVADA SYSTEM OF HIGHER EDUCATION CONTROL #:2707-1516 NEW AWARD DE-FOA-0002707(MINER) PROJECT TITLE: ''ACCELERATED REACTIVE CARBONATION PROCESS (ARCP) FOR ENERGY EFFICIENT SEPARATION OF RARE EARTH MINERALS.'' THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A NOVEL BENEFICIATION PROCESS WITH THE UTILIZATION OF AN ACCELERATED REACTIVE CARBONATION REACTION (ARCP) AND HIGH PRESSURING GRIND ROLLS (HPGR) AND X-RAY TRANSMISSION (XRT) SORTING TO ENABLE IMPROVED MINERAL LIBERATION, ENERGY-EFFICIENT COMMINUTION, AND ENHANCED SEPARATION OF RARE EARTH ELEMENTS (REES) FROM MOUNTAIN PASS DEPOSIT. IN THIS PROPOSED PROJECT, HIGH-PRESSURE GRINDING ROLLS (HPGR) WILL BE USED TO PRE-CRUSH THE REE ORES.
