Imperial Mining (IPG) has filed a series of patent applications.
The applications pertain to the extraction of scandium (Sc) and rare earth elements (REE) from Crater Lake project mineralization.
The patent is for its two-stage hydrometallurgical methods and processes. It was filed with the United States Patent and Trademark Office and Canada Intellectual Property Office.
The company also provided an update on the Crater Lake Scandium Project flowsheet development program, which began in 2022 at SGS Canada, Québec City, as well as Peterborough, and was partially financed from a $245,355 grant from the Québec Ministry of Energy and Natural Resources.
The flowsheet development program focused on optimizing the mineral processing flowsheet by rejecting non-Sc-REE-bearing minerals from the concentrate, then processing the mineral concentrate through the patent-pending high-pressure caustic leach process for recovery of Sc and REE.
During the flowsheet development program, the company invented a patentable process for rejecting olivine (a non-Sc-REE-bearing mineral) from the scandium-bearing mineral concentrate.
The program is expected to be complete by the end of March 2023.
