Study on Mechanochemical Activation-Enhanced Hydrochloric Acid Leaching of Rare Earth Elements from Roasted NdFeB Waste

NdFeB waste is an important rare earth secondary resource, and the current industrial practice primarily employs a hydrochloric acid preferential dissolution method to recover rare earth elements (REEs). However, approximately 1% of REEs (e.g., cerium oxide, neodymium oxide, pras...
