Rare Earth and Phosphorus Leaching from a Flotation

Rare Earth and Phosphorus Leaching from a Flotation

Phosphorite, or phosphate rock, is the raw material of phosphoric acid production. It has also been regarded as the most important secondary rare earth element (REE) resource due to low contents of rare earth elements contained in the ore. In Florida, there is about 19 Mt of phosphate rock mined annually. After beneficiation, the phosphate rock concentrate is utilized to produce phosphoric ...

A review of reagents applied to rare earth mineral flotation

A review of reagents applied to rare earth mineral flotation

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.

US4157296A Flotation process for fluoride minerals

Flotation processes are provided, wherein a vinyl sulfonic acid polymer or an allyl sulfonic acid polymer is added to the pulp in a minor amount as a depressant for constituents which preferably should be floated to a minimum degree. Thus the polymers are effective barite-depressants in the flotation of fluoride minerals and rare earth carbonates.
