In the extractive flowsheet of a metal, the term "resource processing" usually refers to the group of unit operations, involving both physical and chemical processing, which convert the as-mined ore to a compound that is either an end product by itself or an inter-process intermediate for the subsequent production of the metal or alloy or another compound.
Concentration of rare earth minerals from coal by froth flotation
Froth flotation was successful in concentrating REMs existing in a thickener underflow material derived from Fire Clay seam coal which contained around 300 ppm of rare earth elements (REEs). Conditioning with fatty acid followed by processing using multiple stages of conventional flotation produced a final concentrate containing 2300 ppm REEs.

Rare-earth element
Processing ores. All rare-earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation.
