Apr 01, 2021 The best pH for fluorite flotation in either pure water (collectorless flotation) or in the presence of surfactants (froth flotation) ranges from 7 to 11 , , , . It was also shown that pH 9 is usually selected as the most suitable pH regardless of flotation reagents 54,55. This pH value corresponds well to the zero charge point of fluorite. This dissertation investigates the interfacial structure and reactivity of a rare earth mineral in the context of froth flotation. Bastnsite (Ce,La,Nd)FCO3, one of the primary mineral sources of rare earth elements, has been chosen for this investigation. Flotation separation relies on selective adsorption of collector ligands to the desired mineral surface in solution fundamental ...

Mar 17, 2020 Bastnsite, a fluoro-carbonate mineral, is the single largest mineral source of light rare earth elements (REE), La, Ce and Nd. Enhancing the efficiency of separation of the mineral from gangue through froth flotation is the first step towards meeting an ever increasing demand for REE. A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
