2018-9-12 · Agitation leaching is an important extraction process in REE hydrometallurgy. Many processes use leaching methods to extract REE, such as leaching with acids, alkalis and/or salt reagents. These methods typically use agitation tanks, for example, to leach REE by the process of acid roasting of bastnasite with sulfuric acid.
