چکیده
|
Sulfuric acid dissolution of rare earth elements from bastnasite ore was studied after reductive smelting with carbon as a reducing agent at 1600°c. the two-step strategy: 1.carbothermic reduction, and 2.dissolution with sulfuric acid at 70°c was applied under atmospheric pressure aiming at an increased selective extraction of rare earth elements from slag containing rare earth elements.
