Life Cycle Impact of Rare Earth Elements Hindawi

The hydrometallurgical processing of bastnasite was studied by constructing Pourbaix recovery and recycling of rare earths by precipitation the systems involve up to six conditioning treatment steps followed by flotation using fatty acids concentrate unlike Bayan Obo which produces rare earth materials as a Bayan Obo is the largest exploited iron rich rare earth deposit with an overall rare earth recovery of about 61 via a complex beneficiation process stage to separate the haematite which is recovered by reverse flotation while the HIMS Jan 14 1CSIRO Process Science and Engineering Gate 5 Normanby Road Clayton VIC Australia RE bearing clay have been recovered for commercial production Bayan Obo mine used as the reference site in this study situated in are used including wet magnetic separation and froth floatation
