    Bauxite Mills Bayer Process

    In the Bayer process Fig. 2, bauxite received from the mines is crushed to a particle size of less than 25 mm, usually by a hammer mill, blended to obtain a more uniform feed for the process, and stored. From storage the bauxite is metered into wet grinding-rod mills, where spent liquor recycled NaOH solution is used as a grinding medium..more than that reported in 2018, with an estimated value of about 162 million. About 73 of the bauxite was refined by the Bayer process for alumina or aluminum hydroxide, and the remainder went to products such as abrasives, cement, chemicals, proppants, refractories, and as a slag adjuster in steel mills. Two domestic Bayer-process
