Excerpt from Modern American Methods of Copper SmeltingThe collection of papers which forms this book was mostly prepared in moments stolen from more active professional duties, and must subsequently lack the uniformity and completeness which is compatible only with ample leisure and freedom from other more pressing cares.It has been my intention to confine myself principally to facts gleaned from my own experience, and only to touch upon theoretical questions when essential for the understanding of practical facts.As the items of cost, both of construction and of subsequent operation, are amongst the most important of all the practical questions that face the originators of new smelting enterprises, and as these are virtually unattainable to the general public, I have gone into these figures in considerable detail, not calculating expenses as they appear on paper, and when everything is running smoothly, but giving the actual results of building on a large scale, and of smelting many thousand tons of ores under varying circumstances, and in all of the ordinary kinds of furnaces.Owing to the magnitude of the subject, I found it impossible to touch upon the so-called "Wet Methods" without increasing the size and consequent cost of this volume to an extent that might probably peril its circulation.The author desires to acknowledge the valuable assistance of Mr. J. E. Mills, in connection with the geology of the Butte mining district, and to credit Mr. H. M. Howe and Mr. A. F. Wendt with the use he has made of their papers on "Copper Smelting" and on "The Pyrites Deposits of the Alleghanies."But, above all, he has to thank Mr. James Douglas for a thorough and minute revision and criticism of his manuscript just before publication.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
