Most REE minerals, especially bastnäsite and monazite, must be decomposed prior to leaching. Decomposition is commonly done by roasting or baking the concentrate in acid-proof kilns at 200–600°C, the optimum temperature being dependent on mineralogy. Strong sulfuric acid (H2SO4) is blended with concentr…
