摘要

The extraction and processing of rare earth elements (REEs) are of paramount importance due to their critical role in various high-tech and green energy applications. Geopolitical strains in the last decade have created significant volatility in the REE supply chain, with wide fluctuations in pricing and availability of the magnet REE. Commerce Resources, a junior mineral exploration company, is working toward the development of a REE mine (Ashram Deposit) and processing facility to offer an alternative to Chinese REE. This chapter presents an account of the development and optimization of the hydrometallurgical processing portion of the project. L3 evaluated both a hydrochloric acid and a sulfuric acid route. Following improvements in the flotation concentrate recovery and grade, L3 developed a streamlined sulfuric acid bake process for the extraction of REEs.
