Mineral Processing of Rare Earth Ores SpringerLink

2020-3-26  About 95% of the world’s rare earth production comes from bastnaesite, monazite, and xenotime minerals. In many instances, rare earth minerals are found in association with various gangue minerals. The recovery of rare earth values from the lean-grade ores requires several stages of mineral beneficiation and hydrometallurgical unit operations.
