Rare earth elements (REE) are generally extracted from monazite or bastnasite concentrates in either acidic or alkaline media. Many of the processing routes that are generally applicable for rock or mineral deposits are not applicable for all coal-based REE deposits; although, they may find some suitability in specific circumstances. In many scenarios, REE-bearing minerals in coal material are very fine, with individual mineral grains often less than 10 microns. While grinding and separation are challenging at this size, innovations in mineral processing, combined with low cost chemical extraction and separation technologies, are likely to enable even low grade coal-based resources with 200-400 ppm REEs to be economically recovered using environmentally friendly methods. This paper will discuss associated research and development to enable economically viable, efficient recovery of REEs from coal-based resources.
