Excerpt from The Cyanide Handbook
Notwithstanding the fact that so much has been written about the cyanide process since its successful establishment in South Africa in 1890 there still appear to be some aspects of the subject which are only slightly touched upon, or quite inadequately treated, by the many able exponents of the process, and many facts of great value to the practical worker can only be gathered by long and painful search through technical literature. The various mechanical developments of the process have been dealt with by different writers too numerous to mention, and books have been published in which this side of the question is handled in a fairly adequate manner. The chemical aspect of the process has, however, been treated only in a fragmentary and imperfect manner, although valuable contributions to our knowledge of this subject have appeared from time to time, chiefly in the form of papers read before such bodies as the Chemical and Metallurgical Society of South Africa, the Institution of Mining and Metallurgy, and the Society of Chemical Industry.
The aim of the present work is to bring together such scattered information in a handy and accessible form, which will appeal to all workers interested in the process, whether as managers of plants, foremen, chemists, or assayers. Depending as it does on the application of chemical principles, a very important section of the work connected with a cyanide plant is carried on in the laboratory; this department will therefore receive a larger share of attention than is usually given to it in books of this description.
The discussion of the chemical properties, reactions, methods of manufacture, and analysis of cyanide itself, which have been scarcely touched upon in other similar books, will here be dealt with in sufficient detail. An outline will be given of the latest and most approved practice in modem cyanide plants, but without going into minute details of working, which are liable to constant change.
