A new collector for rare earth mineral flotation

A new collector for rare earth mineral flotation

Dec 01, 1997 Due to its high selectivity to rare earth element ions in the weak alkaline region, hydroxamic acid has been used as the collector in rare earth mineral flotation. In our previous papers 9,10, we described experimental studies on the flotation of monazite and bastnaesite from rare earth ores by using a combination of modified hydroxamic acid MOHA and proper modifiers.

A new collector for rare earth mineral flotation

The experimental results of flotation of pure bastnaesite mineral and rare earth ores, and the application experience in flotation plants showed that MOHA is an efficient collector for bastnaesite flotation. MOHA has stronger collector ability and higher selectivity compared to the other commonly used collectors. Through the measurements of zeta-potential, adsorption and infrared adsorption spectrum and in

Surface chemistry considerations in the flotation of rare

Semisoluble salt minerals are characterized by their ionic bonding and are distinguished from soluble salt minerals by their limited solubility in water. One group of semisoluble salt minerals being considered is the alkaline earth salt minerals, including fluorite CaF2, calcite CaCO3 and apatite Ca5F PO43, as well as celestite SrSO4 and barite BaSO4.

Selective flotation of bastnaesite from monazite in rare

Not only effective collectors, but also efficient depressants play an important role in the flotation of rare earth minerals Pradip and Fuerstenau, 1991.. While searching for collectors to selectively float bastnaesite over monazite, investigations were also per- formed in our laboratory to find a depressant that could be used to achieve the ...

Improved Collectors for Flotation of Bastnaesite Journal

Bastnaesite is an important mineral because of its abundance and rare earth content. Calcite and barite are the most common gangue minerals associated with bastnaesite. The importance of finding a suitable collector that can be selective against the gangue minerals without heated conditioning is critical to the advancement of the beneficiation ...
