An outline will be given of the latest and most approved practice in modern cyanide plants, but without going into minute details of working, which are liable to constant change.

Book Description
Excerpt from d104 Book of Cyanide Practice The cyanide process is a subject comprehending many divisions, and one that can best be treated along some phase or with a special point in view. The point in view or purpose of this work is to furnish students, cyanide workers, and those generally and technically interested in the subject, with a practical and technical exposition of the principles and basic practice applicable to cyanidation in general, and not of the particular practice at any plant or locality. An exposition not too technical and complicated or comprehensive for those who are acquiring or about to acquire their technical equipment, nor too superficial for the experienced operator. Intended primarily to guide the first footsteps and early progress of those who hope to eventually operate plants, the author has used simple explanations and many repetitions and references to other parts of the text in the effort to clarify a subject that is confusing, to say the least, to the beginner. Desiring to produce a work that will be of use in actual practice, rather than something to simply add to one's technical library, the author has not kept within academic limitations, but has resorted to homely methods of explanation where deemed advisable. Though going into considerable detail, no branch of the subject has been carried to that point where it should be taken up as a special subject. It aims to lift the careful reader and student to that point where he may intelligently seek further information in the literature on investigations into special and abstruse details of the subject, for which purpose and as an aid to the advanced worker an extended Classified Bibliography of the more accessible literature on the cyanide process is included. Where it has been impossible to give definite figures without going into explanatory details, obviously beyond the scope of this work, figures representing the average or rational extremes in practice have been given. The reader may consider these as carefully selected to represent accurately approved modern practice. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ... section vi useful formulae (1) To find weight of cyanide (or other soluble salt) to be added for making up stock solution to required strength. When the solutions are contained, as is usually the case, in cylindrical or rectangular tanks, the quantity is calculated by measuring the depth in the tank, having previously determined the weight corresponding to a unit of depth. Let D-total depth of solution in storage tank when filled to required point. d-depth in storage tank already filled a-per cent. of cyanide at present in storage tank 6 = per cent. of cyanide in sump or reservoir from which liquid is to be drawn in making up. p-percentage required in final solution t-weight of solution corresponding to unit depth in storage tank.

Book Description
Excerpt from Practical Data for the Cyanide Plant The inspiration for the publication of this volume was in the realization that, while theory and practice of the cyanide process has been ably explained in the standard works on the subject, no attempt has yet been made to collect the practical data, formulae, tables, usual methods etc., in one small and convenient volume which might be carried about by the "Man on Shift." The work is frankly a compilation, with some few diversions from standard practice which long experience has shown to be advisable. It is intended to assist the shift man in understanding the basic reasons for the operations he performs every day, and to give him convenient access to the data he may have to use from time to time. The experienced worker also, it is hoped, will find the work a convenience to him on his travels, containing, as it does, matter which could only be had from a number of standard books on the subject aside from his personal notes. The author fully realizes the deficiencies of the work and request communications from those who feel inclined to suggest the advisability of additions or improvements. The author sincerely hopes that the volume may be an aid and a convenience to the "Man on Shift," to whose especial use he has dedicated his work.

Book Description
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.

Book Description
Excerpt from Cyanide Processes The author's investigations of the Cyanide Process were first confined to Patent Office literature, together with such extracts as appeared from time to time in technical journals and society periodicals. For his own benefit he grouped the numerous articles which gave but a passing insight into the subject. His investiga tions upon the subject made to verify the results as set forth by the various writers convinced him that by grouping the items of importance in connection with the subject considerable light could be thrown on the process and much time saved.

Book Description
Excerpt from The Cyanide Process: Its Control and Operation Much has been written on the cyanide process, but no book now available attacks the subject from the point that is most vital, namely, the laboratory. Every successful process owes its existence to a laboratory, which works out the details of efficient treatment and alters them as conditions demand. The object of this book is to furnish a laboratory guide, both for investigating a new ore and for conducting the laboratory of an operating mill. It should be helpful to the student and beginner, and it is hoped that it may also be of assistance to the more experienced.
