The metallurgy of gold

Description

Sixth edition, Charles Griffin & Co., Ltd., London, 1915. - 601 p.Following an old definition, which can hardly be bettered, a book on the metallurgy of gold should give an account of the extraction of gold from its ores and of adapting it for use. The book would then be useful to students and to metallurgists engaged in their profession. The most important function, however, which a book on metallurgy has to fulfill is to help those who are taking part in attempts to improve the existing practice. Progress in metallurgy depends on the capacity of metallurgists to apply their knowledge of physical science and engineering to the problems presented to them, and in this they are aided by a full understanding of the causes of the phenomena which they observe.Contents The physical and chemical properties of gold Alloys of gold Chemistry of the compounds of gold Mode of occurrence and distribution of gold Treatment of shallow placer deposits Deep placer deposits Ore crushing in the stamp battery Amalgamation in the stamp battery Other forms of crushing and amalgamating machinery Fine grinding Concentration in gold mills Dry crushing Roasting Chlorination The cyanide process - chemical reactions The cyanide process - general methods The cyanide process - special methods and examples of practice The refining and parting of gold bullion The assay of gold ores The assay of gold bullion Statistics of gold production and consumption Bibliography Index
