Hi All, I mixed bauxite (aluminum ore contained 50% Al2O3 and 13% Fe2O3) with strong Sulfuric Acid/H2SO4. We all know both Al2O3 and Fe2O3 soluble in Sulfuric Acid. My question is : how to precipitate Fe2O3 alone, and let Al2O3 be soluble in sulfuric acid?? What to add?? Or how to treat?? Thanks in advance for your kind helps.
