A critical review of the literature on rare-earth mineral flotation suggests the possibility of designing a more selective reagent combination for the beneficiation of Mountain Pass rare-earth ore

(PDF) FLOTATION CHEMISTRY OF A RARE EARTH

The influence of lead nitrate on rare earth flotation in the presence of hydroxamates as collectors has been investigated by a combination of micro-flotation tests and time of flight secondary ion

Rare Earth Flotation Fundamentals: A Review

2001-3-2  As the primary rare earth mineral at two of the world’s largest rare earth mines (Mountain Pass, CA and Bayan Obo, China) bastnasite has been the main focus of rare earth flotation research for some time. During this time, a variety of collectors for the flotation

CMI Invention Disclosures Ames Laboratory

2021-3-15  This invention is the successful development and application of novel collectors for rare earth mineral flotation. Novel collectors enhance TREO recovery, grade and gangue rejection in flotation. Also, much of the testing was performed at ambient temperature and without the use of depressants, which is an advantage over existing industrial rare

Floatation Study of Three Kinds of Collectors Towards

2011-7-8  Abstract: Under different conditions,the floatation laws of sodium oleate,salicylhydroxami acid and Maoniuping rare earth collector(principal components are hydroxyl naphthalene-containing hydroximic acid) as collectors for bastnaesite are researched and the relative flotation mechanism are studied.Experimental results show:the dosage of collecting agent and sodium silicate has great

2015-2-10  hydroxamate flotation of REE minerals has not been limited to n‐octanohydroxamate and Xu et al., 2002, Ren et al., 1997 and Cheng et al., 2007 reported the use of naphthalenic hydroxamate collectors in rare earth flotation.

Bastnaesite, Barite, and Calcite Flotation Behaviors

The flotation of bastnaesite, as a major mineral source of rare earth elements, attracting much attention in the mineral processing field, is challenging owing to the natural flotability of calcium-bearing minerals. To promote the application of flotation, we systematically investigated the flotation behavior of bastnaesite, barite, and calcite, with salicylhydroxamic acid (SHA) as the

Mining and mineral processing. The market is constantly challenged to achieve greater value from operations at every stage of mineral processing including mineral suspension and slurry handling, flotation separation and other enrichment technologies, mineral concentrate improvement, tailings management, and water recovery.

Minerals Free Full-Text Effect of Depressants and

A full factorial experimental design was conducted to investigate the effect of temperature and depressants on the flotation of monazite and bastnaesite from carbonate gangue minerals. Temperature, sodium silicate, and guar gum dosage were examined. Mineral reconstruction from energy-dispersive x-ray fluorescence (EDXRF) data was performed to quantify bastnaesite, monazite, and gangue mineral
