The manufacturing process of alumina from bauxite was proposed by K.J. Bayer. In this process, bauxite, along with sodium hydroxide is heated at high pressure (∼30 atm) and temperatures between 373 and 593 K resulting in sodium aluminate solution in accordance with the following reaction: (2) Al 2 O 3 ·xH 2 O+2NaOH→2NaAlO 2 …

Since the installation of the dross presses, the consistency of the dross has improved. Prior to the press installation, the size of the dross varied from fine material to extremely large blocks up to 60″ in width and up to 8000 pounds in weight. This made processing the materials at Al Rec very difficult and inefficient.
