Aluminum Extraction

  • G. Alan Wolstenholme

Abstract

In this chapter, the commercial molten salt processes now used in extracting and refining aluminum are outlined, together with the scientific principles on which these are based. The economics of aluminum production are also considered, with particular emphasis on the worldwide efforts being made to save power and to reduce production costs by improving the design and operation of reduction cells
