The Bauxite, AR facility was opened as a bauxite refinery in 1952. In 1954 and later in 1959, parts of Alcoa's chemical processes in East St. Louis, Illinois were transferred to the Bauxite facility. The facility acted as a combination chemical and refining plant until the Arkansas bauxite
THE ENEXAL BAUXITE RESIDUE TREATMENT PROCESS:
2016-3-1 Keywords: Bauxite residue, Red Mud, Bayer Process, mineral wool . Abstract . The main by-product of the Bayer process is the bauxite residues (BR), a red slurry consisting of the un-dissolved portion of the bauxite ore. On a dry basis BR are produced at an almost 1:1 mass ratio with alumina, amassing to a total of 100 to 120 million tones
