2020-4-29articleosti1439143 title Improved Collectors for Flotation of Bastnaesite author Everly Dylan and Anderson Corby and Bryantsev Vyacheslav and Jansone-Popova Santa abstractNote 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.
Flotation has been at the heart of the mineral processing industry for over 100 years addressing the sulphide problem of the early 1900s and continues to provide one of the most important
Collectors some of the most important flotation reagents used in the flotation process are used to modify the surface properties of minerals. A collector is a chemical that selectively binds to the surface of target minerals and imparts hydrophobicity to those mineral particles a necessary condition for air
2015-2-10The recovery of rare earth elements REE is fast becoming of significant interest globally. Modern research and development programs outside China towards the optimiation of REE mineral recovery by flotation have been lacking. Due to the mineralogical nature of many hosting deposits the separation and recovery flotation flowsheets can be

The design and development of selective flotation collectors has been the key to the remarkable success of flotation in beneficiating complex difficult-to-process ores. Sustained research efforts in the field over the past hundred years have led to delineating the scientific basis of selective mineral flotation in terms of the crystal chemistry and the surface and colloid chemistry of
Bastnaesite a rare-earth fluocarbonate was separated from associated calcite and barite gangue minerals in the Mountain Pass CA rare-earth ore beneficiation plant by froth flotation using fatty acids tall oil collector lignin sulfonate depressant and soda ash modifier after high-temperature steam conditioning with reagents. Starting with a feed grade of 7.6 REO concentrates having a
