| Abstract Scope |
Rare earth elements are found in many geological settings. Peralkaline volcanic mineralization is found in the Port Hope Simpson Critical Materials District in Labrador, Canada. Minerals such as allanite and fergusonite are found in abundance along with minor chevkinite, bastnasite and monazite. In some deposits, zircon is present in significant concentrations. The complexity of these materials and the high intrinsic values contained require using every tool in the metallurgical toolkit in order to extract and recover the critical materials present. Conventional mineral processing, hydrometallurgical extraction and solvent extraction separation are all required to maximize the potential values of the natural deposits. |
