Abstract
The objective of this paper was to evaluate the extraction of cerium, lanthanum, and neodymium by exploring different leaching conditions with hydrochloric acid and sulfuric acid from a dephosphorized monazite concentrate obtained from alluvial gold mining waste from the Bagre-Nechí mining district in Colombia. The highest element extraction yields are achieved with H2SO4 as the leaching medium versus HCl at all evaluated concentration, time, and temperature conditions. The addition of 10% (v/v) H2O2 was found to increase rare-earth dissolution up to 93% in the H2SO4 medium. Thermodynamic analysis indicates that H2SO4 solutions show a higher capacity to solubilize REEs as opposed to HCl solutions, thus supporting the experimental results.
