6. Aluminum cycle - Wikipedia

   en.wikipedia.org/wiki/Aluminum_cycle

   Aluminum is harvested from gibbsite, boehmite, and diaspore which make up bauxite. [2] The aluminum cycle is the biogeochemical cycle by which aluminum is moved through the environment by natural and anthropogenic processes. The biogeochemical cycle of aluminum is integral with silicon and phosphorus.
