  • ALUNITE Potassium Aluminum Sulfate Hydroxide

    ALUNITE Potassium Aluminum Sulfate Hydroxide

    Alunite is also known as alumstone and is a source of the chemical known as alum, KAlSO42 - 12H2O.Some alunite has also been used to recover potassium and aluminum. Alunite forms from the action of sulfuric acids upon potassium rich feldspars in a process called alunitization.The sulfuric acids accompany hydrothermal solutions, usually rich in certain ore metals.
