  • The History of Aluminum and Charles Martin Hall

    Jan 28, 2019· Aluminum is the most abundant metal element in the earth's crust, but it is always found in a compound rather than an easily-refined ore. Alum is one such compound. Scientists tried Aluminum is the most abundant metal element in the earth's crust, but it is always found in a compound rather than an easily-refined ore. Alum is one such compound. Scientists tried to tease the metal out of alum, but the process was costly until Charles Martin Hall patented an inexpensive method to produce aluminum in 1889.

  • Aluminium production process

    The ore is loaded into autoclaves and treated with lime–caustic soda. Aluminium oxide appears in the resulting slurry while all the admixtures settle to the bottom as red mud. The sodium aluminate solution is stirred in precipitators for several days, eventually pure alumina or Al 2 O 3 settles at the bottom. REDUCTION PROCESS.
