30-07-2018· Improved Flotation Separation Of Rare Earth Ore Sbirgov. A critical step in the extraction of elements from ore especially rare earth elements that are found in complex minerals is separation froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineralwater
Rare-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.
