Chapter 2. Production and Processing of Aluminum
Fig. 2.2 shows that the production of alumina is a complex chemical process. The alu-mina content of bauxite ores varies from one deposit to another, and methods of treat-ment differ accordingly (see 16.1.2). This means that each alumina plant is almost tailor-made to suit a particular bauxite. The processes are nevertheless basically similar ...

How Do Water Softeners Work? + System Flow Diagram
A water softener is a water treatment system consisting of two tanks: a resin tank and a brine tank. Water softeners work by using a process called ion exchange – specifically, a type of ion exchange known as cation exchange. Here are the steps involved in this process: Hard water enters the water softener's resin tank, which contains a bed ...

Our process
The solid impurities settle as a fine mud in thickening tanks. This red mud is a by-product of the process. After several washing stages to recover caustic soda, this residue is neutralised with sea water and pumped to storage dams. The clear solution is transferred to Precipitation to recover the alumina contained in it.
