IPG:CC - Miner Files Patents for Extraction Process

This multi-mining exploration company is filing a patent for rejecting %Olivine from the scandium-bearing mineral concentrate. The mineral response to conventional mineral processing techniques, making it difficult to separate and diluting the Sc-REE grade of the concentrate.

%ImperialMiningGroup ( ) () announced the filling of patent applications for its two-stage hydrometallurgical methods and processes for the extraction of scandium (Sc) and rare earth elements (REE) from Crater Lake project mineralization in its press release today.

The patent, was filed in December in both the United States and Canada. The flowsheet development program was focused on further optimization of the mineral processing flowsheet by rejecting olivine, a non-Sc-REE-bearing mineral from the mineral concentrate and processing of the olivine-depleted mineral concentrate through the patent-pending high-pressure caustic leach process for recovery of Sc and REE.
