  • ALTEK | Total Aluminium Dross Processing

    ALTEK | Total Aluminium Dross Processing

    2019-11-11Salt slag differs from aluminium dross due to it having a lower aluminium content and a higher temperature when taken out of the furnace. ALTEKs salt slag press is designed and programmed to match these differing needs so as to maximise aluminium extraction, and therefore saving you money and increasing aluminium recovery.

    Chapter 2. Production and Processing of Aluminum

    1999-5-7The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide Al 2 O 3 called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.
