چکیده
|
Dissolution of rare earth elements from bastnasite ore was studied using different leaching agents such as sulfuric acid, hydrochloric acid, acetic acid, citric acid and sodium hydroxide at 70°c, with 1mol/l, solid/liquid ratio of 0.05 between 30 and 180 min. the one-step direct leaching strategy was applied under atmospheric pressure aiming at selective leaching of rare earth elements from a matrix of iron oxides in which the rare earth elements – carbonates & flourides – are embedded.
