Given the geographical imbalance distribution and supply shortage of rare earth elements (REEs) in renewable energy processes, magnets, many high-tech technologies, etc., researchers are increasingly seeking to recover REEs from unconventional sources such as coal by-products. This article provides a brief overview mode occurrence its association coal. It also discusses existing potential benef...

Antisolvent crystallization is a separation technology that separates the solute from solvent by addition of another solvent, in which sparingly soluble. High yields are achieved using higher antisolvent-to-aqueous ratios, but this generates supersaturation, causes excessive nucleation. This results production smaller particles, difficult to handle downstream processes. In work, effect varying ...
