    Aluminum Production and Processing. Primary production involves mining bauxite deposits from the earth, chemically refining it into pure aluminum oxide and performing electrometallurgical processing to ultimately form aluminum. Secondary production makes new aluminum from recycled scrap that for many products, like cans, is completely …

  • Mining and Refining – Process

    The process stages are: 1. Milling. The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage. Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills …

  • Bauxite: The principal ore of aluminum.

    Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite. The aluminum is precipitated out of solution in the form of aluminum hydroxide ...
