Production of rare earth oxides from raw ore in fluidized

25/05/2020 Though, the production of rare earth oxides from a rare earth bearing ore through the calcination is challenging because each rare earth mineral holds a different thermal behavior. For instance, despite its decomposition at relatively low temperature, 400 °C, bastnäsite produces two rare earths phases: rare earth oxide and rare earth fluoride [21] .

Combined approaches for comprehensive processing of rare

01/11/2012 Technologies for processing rare earth ores (Chuktukon deposits, East Siberia, Russia) have been developed. The ores are composed of iron-manganese oxides and contain 3–7% of rare-earth oxides in the phosphate form (turnerite, florencite) and 0.5–1% of niobium oxide (chalcolamprite). These ores are refractory and do not lend themselves to concentration, therefore various processes

METHOD FOR PROCESSING RARE EARTH FLUOROCARBONATE

The bastnasite ore from the mines generally contains about 10 percent by weight rare earth oxides. Prior to processing the ore by digestion, it is preferable to dress the ore and concentrate the ore so as to provide a rare earth oxide concentrate having at least about 60 percent by weight rare earth oxides, and preferably, at least 70 percent by weight rare earth oxides.
