The most important reason for metal losses is not the oxidation of aluminum, but the entrapment of liquid metal and agglomeration of oxide films. An increasing metallic aluminum content supports the growth of the dross granules. Theoretically, Al 2 O 3 contains about 53% aluminum, so fractions with a lower aluminum content are predominantly oxide.
