Book Review - The Chemistry Of Gold Extraction

Reviewer: R. Graham The chemistry of gold extraction by John Marsden and lain House. Elis Horwood Series in Metals and Associated Materials. Chichester, Elis Horwood. £80. The chronology has been well researched, and the book defines al the milestones. It is a pity that there is no map of the early gold finds in South Africa, which would have offered a comparison with those shown of Australia and the USA. Nevertheless, the 'Pre-cyanidation, Cyanidation and Technical Development' eras fall logically into place, and reflect on the advances in social history and civilization, as well as in technology.
