 · Rare earth minerals such as monazite exist in coal and have grain sizes smaller than 5 µm. In this study, froth flotation was successful in concentrating rare earth minerals existing in a thickener underflow material derived from Fire Clay seam coal that contained around 431 ppm of total rare earth elements (TREE) on a dry ash basis.

Flotation Reagents Collectors | ArrMaz

Flotation Reagents Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.

Highgrade rare earth mineral concentrates were produced with the HHS process ranging from ppm of total rare earth elements, depending on the method and reagent. Additionally, the HHS process produced copper concentrates assaying greater than 30% Cu for both artificial and real feed samples, as well as, between 1020% Cu for waste samples, which all performed better than flotation.
