A review of reagents applied to rare

16/03/2020Rare-earth mineral (REM) deposits can be broadly classified into four geological environments: carbonates, alkaline/peralkaline igneous rocks, placers and ion adsorption clays. Apart from ion adsorption clay deposits, which require no mineral processing steps, froth flotation is the most applied beneficiation technique.

Critical raw materials such as copper, cobalt or rare earths often appear in their deposits as increasingly smaller ore grains. This means that they are too small for the usual separation by flotation. The FineFuture project partners now want to research the flotation of very fine mineral particles and develop new technological solutions for it.
