Separation and Purification Technology, 2019
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

Applied Clay Science, 2022 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.

Role of minerals properties on leaching process of weathered crust elution-deposited rare earth ore
Journal of Rare Earths, 2015Abstract Granite belonged to intrusive rock and volcanic was extrusive rock. There may be many differences in their degree of weathering and mineral chemical composition. The present study investigated the minerals properties and the leaching mechanism of the granitic weathered crust elution-deposited rare earth ore from Longnan Rare Earth Mine area (

Abstract In this paper, the kinetic of leaching rare earth from the weathered crust elution-deposited rare earth ores with ammonium sulfate solution was investigated. The effects of the main leaching parameters such as temperature and ore particle size on leaching process were examined and discussed in order to elucidate the kinetics and mechanism of
