Abstract Release of the remaining ammonium salts from the weathered crust elution-deposited rare earth ore (WCE-DREO) would pose a serious threat to the environment. Thus, in this study, the adsorption and desorption performances of the WCE-DREO and four minerals that composed it were investigated to select an efficient eluent for the remained ...

Process optimization on leaching of a lean weathered crust elution-deposited rare earth ores
International Journal of Mineral Processing, 2013Abstract The process on leaching of rare earth from the lean weathered crust elution-deposited rare earth ores with ammonium sulfate solution was elucidated and optimized with the chromatographic plate theory. The effects of the flowrate, the packed ore height, the concentration of leach reagents and leach reagent consumption on leaching performance ...

Effect of a novel compound on leaching process of weathered crust elution-deposited rare earth ore
Minerals Engineering, 2018Abstract The leaching process of weathered crust elution-deposited rare earth ore is a typical noncatalytic heterogeneous reaction in liquid–solid systems. In order to intensify the leaching process of rare earth and reduce the impurity leaching accompanying with rare earth, ammonium sulfate and ammonium formate were mixed as a novel compound ...

Abstract This present study focused on investigating the content and relative enrichment multiple of rare earth elements (REEs) in different terrain of weathered ore body, and the value of light rare earth elements/middle and heavy rare earth elements (LREEs/HREEs), in order to understand the mobilization and redistribution of HREEs. Furthermore, the

Abstract Weathered crust elution-deposited rare earth ores are rich in the middle and heavy rare earths. The present study investigated the content of exchangeable aluminum and the exchangeable rare earth in the different layer of orebody and the partitioning of rare earth was determined as well to understand the mode of occurrence of rare earth ...

Abstract Role of initial moisture content of ore was discussed to improve the leaching process of weathered crust elution-deposited rare earth ores, especially the difficult-to-permeate rare earth ores. Effects of the initial moisture content, the ammonium sulfate concentration and the liquid/solid ratio on the leaching efficiencies of rare earth and

Leaching Process and Mechanism of Weathered Crust Elution-Deposited Rare Earth Ore
Mining, Metallurgy & Exploration, 2019The leaching processes and mechanisms of weathered crust elution-deposited rare earth (RE) ores with ammonium sulfate were investigated for their high efficiency and low consumption exploitation. The leaching process is a typical reversible heterogeneous ion exchange reaction in liquid–solid systems.
