Abstract
: The weathering crust ion adsorption rare earth ore sample was processed to mm， and 35 g / L ammonium
sulfate solution (pH ) was used as the leaching agent to extract rare earth elements in the leaching phase. The effects of
sample size， concentration and dosage of leaching agent， acidity of leaching agent， leaching method and leaching time on
the extraction of rare earth elements in leaching phase were investigated. The optimal experimental conditions were
determined. The total amount and component of rare earth elements in the leaching phase were determined by ind
