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

Andrew Ruys, in Alumina Ceramics, 2019. 3.7.6 Recovery of calcium silicate (Portland cement) from red mud produced by the bauxite sinter process. The bauxite soda/lime sinter process, used for low-gibbsite high-silica bauxites, is discussed below in Section 3.8.One of the by-products of the sinter process is calcium silicate 2CaO·SiO 2, also known as Portland cement.

Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

The Process of Mining Bauxite - Dajcor. The Process of Mining Bauxite. by Dajcor Aluminum. Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is found in a belt around the equator and is generally extracted by open-cast mining.
