Book Description
Excerpt from Metallurgy of Copper My aim in preparing this book has been to furnish a treatise on copper which will meet the demands of the metallurgist of to-day. In order to do this, it has been necessary: to present the leading physical and chemical facts about the metal, its alloys, and its compounds which are of metallurgical importance; to record from the older practice that which is of lasting value; and to give the details of the present modes of operating. Though we have several books treating of certain branches of the metallurgy of copper, such as the valuable volumes of Peters, Greenawalt, and others, there does not exist a modern book which covers the entire ground as the present work aims to do. In the study of processes there are given the principles and the practice. The discussion of principles is confined to the essential points; for an extended presentation the reader is referred to my treatise on General Metallurgy. The examples of practice are drawn mainly from the United States. The text and footnotes will show that the technical literature on copper has been covered. The details of practice, not recorded in print, have been obtained through visits to and detailed studies of the leading copper smelteries and refineries of the United States; additional information has been available through correspondence. The tables giving the working data of the leading plants of the United States, Canada, Mexico, Germany, and Australia show the extent of the field which has been covered. In all my visits and correspondence I have met with the greatest cordiality and liberality. I wish to express here my obligation to the heads and officers of the different smelteries and refineries for the assistance they have rendered me in my task; without this cordial and liberal aid it would not have been possible to prepare this treatise. In working out the details, especially in the large number of calculations, I have been much assisted by the collaboration of my colleague Professor C.R. Hayward. The reading of the page-proof by Professor G.A. Roush detected errata which had escaped my own revision. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The Hydro-Metallurgy of Copper Along period has elapsed - to be measured by centuries - since the Hydro-Metallurgical Treatment of Copper Ores was originated at the Rio Tinto Mines. Several processes have since been evolved, as the result, in large measure, of the investigations of manufacturers of sulphuric acid, who employ iron sulphides containing a low percentage of copper for the production of the acid, and who made it a special study to extract the residual copper from the burnt pyrites and cinders. The successful solution of that problem led to the adaptation of various leaching processes at a few low-grade copper mines, where smelting operations would have been too costly for the profitable treatment of the ores. The application of the various lixiviation processes has had only a limited scope up till now; but it is more than likely that in future more attention will be given to them, owing to the necessity which (it may be expected) will arise for an economical exploitation of the low-grade copper deposits occurring in various parts of the globe. These can be made to pay by leaching - which, when judiciously applied, is cheaper than smelting - and in view of the increasing consumption of copper many of these hitherto undeveloped sources of supply will no doubt be opened up and utilised.

Book Description
Excerpt from The Practice of Copper Smelting Owing to the great developments which the dry metallurgy of copper has experienced during the past twenty years, any attempt to write a complete work upon the subject would result in an encyclopedia rather than a handbook. I have, therefore, believed it best to introduce comparatively few illustrations of processes, but to select these from the best modern practice, and to study them in detail. A book of this nature cannot be written without the cooperation of the owners and managers of a large number of metallurgical plants operating under a variety of conditions, and this assistance has been extended to me in the most liberal manner.

Book Description
Excerpt from The Chemistry and Metallurgy of Copper: Including a Description of the Principal Copper Mines of the United States and Other Countries Having been engaged for some years in the analysis of ores of copper, and in the determination of chemical questions con cerning that' metal, in connection with a large and well-ap pointed smelting establishment, the author has acquired ex perience which he has thought might be of service to others engaged in the same pursuit. He has also been led to believe that some information, in a form accessible to the masses of our people, on the subject of mines, veins and ores of copper, with the known laws of their occurrence, might be of service in assisting in the development of this very important part of the mineral wealth of our country. The present work is designed to supply what the author be lieves to be a desideratum. His aim has been to popularize it sufficiently for the use of those who have not hitherto made the sciences of chemistry and geology a special study, with out so neglecting details as to render it of no value to the ex pert in these studies. How far he has succeeded in this at tempt is for the public to judge. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Metallurgy: Instruction Paper For centuries iron has been the most useful metal known to man. In the earliest periods of history, stone implements were used; later bronze, an alloy of Copper and tin, replaced stone. After a time men found a way to extract iron from its ores, and the Iron Age began. As nothing has yet been discovered, or invented, to take the place of iron in the arts, the Iron Age has continued until the present day. The process of separating, or extracting iron from its ores; of smelting and refining it; and of making it into its most useful form, steel, is called the metallurgy of iron. From small beginnings, this art has gradually increased to its present importance. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Handbook of Metallurgy, Vol. 1: Copper, Lead, Silver, Gold IT is a curious fact that there does not exist in the English language a single complete treatise on Metallurgy. There are a number of smaller text-books, mainly adapted to the use of students, which cover the entire field, but make no pretence of describing it with any thoroughness of detail; and there are a number of very admirable works dedicated to the metallurgy of individual metals. Had my respected teacher, the late Dr. John Percy, ever carried out his magnificent idea of a comprehensive series of volumes on this subject, the ideal of. An exhaustive work on Metallurgy would have been produced, although its bulk would have attained the formidable dimensions of a small library in itself - an advantage perhaps to the specialist, but a less commendable feature for those who have to deal with general Metallurgy. Such being the position of our literature of this subject, I venture to think that I am rendering the English metallurgist a distinct service in submitting to him a translation of the most recent and most exhaustive work on the subject in any language, from the pen of that eminent metallurgical authority, Dr. C. Schnabel, of Clausthal. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Analysis of Copper: And Its Ores and Alloys NO attempt is made to give a complete list of apparatus used in metallurgical analysis but a few special improvements which have been adopted in large copper laboratories to facilitate rapid work are described. All apparatus should be suited to the character of the work, whether it be ore-assaying or the delicate estimation of traces Of impurities in refined metal, an Operation in which results are calculated to a ten-thousandth of One per cent, or one more decimal place than is usual in report ing tests Of iron and steel. TO permit this degree Of accuracy in the examination of refined copper, the bulk of final solutions and the size of filter papers and containers should be kept as small as possible without undue sacrifice Of speed.
