DOWNLOAD EBOOK →Excerpt from More Recent Cyanide Practice The success which attended the publication of 'Recent Cyanide Practice, ' edited by Mr. T. A. Rickard, and printed in 1907, together with repeated calls for a volume covering in the same manner still later developments in cyanidation, has led to the compilation of this book. In it the development of cyanidation from October 1907 to July 1910 is reflected in articles contributed originally to the Mining and Scientific Press. The individual articles cover a wide range and illustrate the development both of theory and practice in the period covered. They have come from all parts of the world and the contributors include the leaders in the application of cyanide to metallurgy. No attempt has been made to harmonize conflicting views, and as little change as possible has been made in the original wording of the authors. The necessary limit to the size of the volume has precluded reprinting of many other worthy and interesting papers, for which readers must refer to the files of the Mining and Scientific Press. In making the selection of material I have had the valued assistance of Mr. Bertram Hunt. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

DOWNLOAD EBOOK →Excerpt from Cyanide Practice: 1910 to 1913 This is the third in the series of books'that began with 'recent Cyanide Practice' edited by Mr. T. A. Rickard, and printed in 1907, and which was continued by 'more Recent Cyanide Prac tice' edited by Mr. H. Foster Rain and printed in 1910. The plan of all three books is the same. They include articles on all phases of current cyanide practice based upon experience in all parts of the world. In the main the papers here reprinted were first pub lished in the Mining and Scientific Press. One or two related in timately to discussions in the columns of the Press, have been taken from The Mining Magazine, and the South African Mining Journal to which acknowledgment is gladly made here and in the body of the text. In preparing the various papers for use in this book a number have been materially condensed and my own have been revised. Instead of the articles being arranged according to dates, they are given under their proper heads, from the chemistry of the process to the clean-up, although the dates on which they were published are also given. This arrangement should find favor with readers, who will be able more readily to find any particular depart ment or process. The time covered by the articles here brought together extended from July, 1910, to January, 1913, except that a few appearing in the Press in the early part of the present year have been included. The necessity of restricting the size of the volume has made it necessary to omit a number of excellent papers of local or temporary importance, and also many that deal especially with ore dressing and stamp milling rather than cyanidation proper. A number dealing especially with cyanidation in Mexico having already been printed in Mr. Ferdinand mccann's work 'cyanide Practice in Mexico' have also been left out. Even with these omissions, this book will, I hope, serve as have its predecessors, the main purpose of furnishing in convenient form a general view of the best in current cyanide practice.

DOWNLOAD EBOOK →Excerpt from Recent Cyanide Practice From the early beginnings of civilization gold has been highly prized and eagerly sought after. Human life has been freely sacrificed in its acquirement from natural sources, as well as in its forcible seizure from those who already possessed it. The 'age of Gold' was not necessarily the 'golden Age, ' for the noble metal, in its unique and barbaric splendor, has symbol ized much that has been unworthy in national and individual aims and ideals. With the advent of the industrial age gold was destined to take a new place in the world's history as the great medium of exchange, the great promotor of industry and com merce. While individual gain still remained the propelling power toward its discovery and acquisition, every fresh discovery led directly or indirectly to the freer interchange of the products of industry, and thus reacted favorably on the industrial and social conditions of thetime. So long as the chief Supplies of gold were Obtained from alluvial deposits by the simple process of washing, the winning of gold almost necessarily continued to be pursued by individuals, or by small groups of workers, who were mainly attracted by the highly speculative nature of the occupa tion. These workers endured the greatest hardships and ran the most serious personal risks, drawn on from day to day by the hope that some special stroke of good fortune would be theirs. This condition prevailed also in fields in which the reef gold occurred near the surface, where it was easily accessible without costly mining appliances, and where the precious metal was loosely associated with a weathered matrix. These free-milling ores could be readily handled by crushing and amalgamation with mercury, so that here also no elaborate organization and no great expenditure of Capital were necessary. A third stage was reached when the more easily-worked deposits above the water-line had been worked out. Not only were more costly appliances and more elaborately organized efforts required to bring the ore to the surface, but the ore, when obtained, contained.
