Following mineral processing beneficiation, the concentrate is sent to extraction. In the case of bastnaesite, the material from flotation is a rare earth fluorocarbonate that must be dissolved to an aqueous form that can be separated to individual rare earths or groups of rare earths through ion exchange or solvent extraction.
