Chapter 2. Production and Processing of Aluminum

1999-5-7  The extraction of aluminum from its ore and subsequent processing into finished prod-ucts takes place in a series of successive operations, each largely independent of the other. Generally the various processes are carried out at different plant sites. A summary of production steps from the bauxite mine through casting is given in Fig. 2.1.
