Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Ore Dressing, Vol. 3 of 4 Ore dressing appeared as a two-volume book in 1903. Since that time advances in the art of concentrating ores have been exceedingly rapid and in some instances well-nigh revolutionary. Investigations have been made for the purpose Of explaining the principles of ore separation, new concentrating devices have been invented and installed in the mills, and the mills themselves have been greatly improved. For these reasons the time seems to have come to bring the subject up to date. When this present work was started in Octo ber, 1906, it was thought that something in the nature Of a small supplement or appendix would suffice and on this basis the collection Of material was under taken. It soon became apparent that the new work would rank in size with Volumes I and II and hence naturally receive the titles Of Volumes III and IV. The idea of revising and rewriting Volumes I and II seemed to be prohibited by reason of the fact that the machines and the mills are so completely inter woven on almost every page that no method of revision appeared adequate to the task. The new work has therefore taken the form of Volumes III and IV in which the subject-matter of Volumes I and II is added to chapter by chapter. In selecting machines for description the effort has been made to take only those machines that have found practical application. The four volumes have been indexed together and the complete index is inserted in each volume. Another feature of the book that will be noted is the insertion Of the mill numbers in a prominent place at the top Of the pages in Chapter XLI. It is hoped that both of these changes will add to the convenience and usefulness Of the book. In Chapter XLI there will be found described ninety-four mills represent ing milling practice in the principal mining centers of the world. Many of these mills are given in great detail and contain figures as to costs, power, water, etc., that should be of the utmost value. Care has been taken in index ing to make this information available. Throughout this chapter tonnages are given in tons of pounds unless otherwise stated.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Text-Book of Ore Dressing My competence in the subject lies to some extent in my own work and observation, but much more in the study of the published work and experience of others. Teachers and students to-day have at their disposal valuable Transactions of Mining and Metallurgical Institutions, and admirable technical Periodicals; upon such I have largely drawn, making endeavour always to give specific acknowledgement. Beyond this, to cover all the indebtedness for which no Specific reference is possible, and such references as have unwittingly been overlooked, I gratefully make general acknowledgement. I am likewise greatly indebted to my colleagues of the Imperial College, and particularly to Professor L. H. Cooke, and Mr. B. W. Holman, of the Mining Department, for advice and assistance, always insisting, however, that my good colleagues are not involved in any such crudities of statement or treatment as may be deemed to exist. To Mr. H. G. Dines, also, I desire to express my thanks for valuable help with the illustrations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Handbook of Ore Dressing, Vol. 1: Equipment and Practice To define the scope Of ore' dressing logically and authoritatively in harmony with existing definitions is an impossibility. The published interpretations are so varied, and encroach, in many instances, on recovery processes, that a new departure is per missible. A permanent and radical alteration in interpretation is preferable to an attempt to expand periodically the definition, so as to embrace or exclude new treatment processes; and it is suggested that the subject may be considered as that branch of metallurgy covering the reduction or other mechanical han dling of the ore whereby one or more products are obtained in a condition to be treated for the isolation of their valuable contents by amalgamation, concentration, wet-chemical, smelting, or other process of recovery.

This book was released on 2018-02-28 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Theory and Practice of Ore Dressing In this work an attempt has been made to cover in a single volume the whole subject of ore dressing as applied at metalliferous mines in western America. The subject is treated in a manner designed to be of value and assistance to several classes of men engaged or interested in the treatment of ore by concentration processes. While the book is written largely as an aid to the mine manager or engineer in charge of mining enterprises, it is believed that the millman also will find in it much of value relating to the care of machines intrusted to his charge. It is not expected that the work will displace the hard-earned experience of the metallurgical engineer, but a man of that class will find in the book many useful and practical data. The needs of the student have not been forgotten, and a sufficient amount of theory has been introduced 'to give him a comprehension of some of the underlying principles of the art.

Book excerpt: Excerpt from The Dressing of Minerals I need only add, that wherever I have described any appliance as made by some particular firm, I do not thereby mean to imply that this make is necessarily superior to similar machines made by others, my selection having been guided mainly by the desire to present well-marked typical examples of the various appliances. A point of consider able difliculty arises with respect to appliances that have been only recently introduced; as a rule, whenever the machines appeared to be designed in accordance with sound principles, I have referred to them briefly, and have stated that they had been in use for too short a time to enable a fair judgment to be formed concerning them.
