Cyanide Practice In Mexico PDF Download

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.
