In reverse flotation, proper reagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting) Aeration is added through spargers at the bottom of the flotation cell The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow
Froth flotation is commonly applied to the beneficiation of rare earth ores due to the fact that it is possible to process a wide range of fine particle sizes and the process can be tailored to the unique mineralogy of a given deposit
Rare Earth Flotation Review Literature on the flotation of rare earth oxide minerals is a relatively limited This is especially true with regard to fundamental flotation research, although, as the demand for rare earths continues to grow, the amount of research in the field is increasing rapidly
For more than a century now, flotation has been at the heart of the mineral processing industry In this month’s SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global industry
beneficiation and recovery Monazite is the second most important rare earth mineral that can be further exploited In this study, the surface chemistry of monazite in terms of zeta potential, adsorption density, and flotation response by microflotation using octanohydroxamic acid is determined
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 .
Rare Earth Minerals Processing There are two major REE ore minerals from which predominantly LREE can be extracted with relative ease: bastnaesite and monazite Bastnaesite, a fluorocarbonate mineral and monazite, a phosphate, contain predominantly either cerium, lanthanum or yttrium
