Book Description
Excerpt from The Metallurgy of the Common Metals: Gold, Silver, Iron, Copper, Lead, and Zinc This outline of the metallurgy of the common metals, namely, gold, silver, iron, copper, lead, and zinc, is devoted to the description of processes for winning these metals from their ores and then refining them. The metallurgy of iron is treated only to the point where pig-iron is obtained. Following the description of ores, as well as of the fuels used in smelting them, and the materials of which the furnaces are con structed, we come to sampling, for the determination of the exact value of the ore before treatment. A chapter has been devoted to the subject of thermo-chemistry as applied to igneous methods of extraction. The winning or reduction of' the various metals is then taken up in order, and is followed by. A description of the methods of refining them. Attention is then given to commercial considerations, since the processes must be conducted in a profitable way.

Book Description
Excerpt from The Metallurgy of the Common Metals: Gold, Silver, Iron (and Steel), Copper, Lead and Zinc Since 1913, the date of the last edition, such radical changes and improvements have been made in the-metallurgy of the common metals, that this edition of 1921 has been largely rewritten to bring it in accord with present practice, as will be seen by examination of the following pages. Great pains have been taken to clearly set forth underlying principles and at the same time to give the details of methods and of metallurgical equip ment, and their cost. It is realized that, due to the rapid advance in prices, the costs of operation have lately been subject to serious modification. A chapter has been devoted to questions of the economic situation of the business of metallurgy. Little attempt has been made to describe methods not now in use.

Book Description
Excerpt from A Textbook on Metallurgy of Gold, Silver, Copper, Lead, and Zinc: Surface Arrangements at Reduction Works, Ore Dressing and Milling, Sampling Ores, Roasting and Calcining Ores, the Cyanide Process When the mercury becomes sickened it refuses to act upon the gold, and hence the gold is not recovered by this process. If, therefore, it is possible to keep the mercury bright and active, as may be done by adding chemicals, a larger percentage of precious metals can be recovered.

Book Description
Excerpt from Manual of Assaying: Gold, Silver, Lead, Copper It is my sincere belief that there is no book in the English language on the subject of assaying which occupies the space that this little manual tries to fill. A number of such publications fail to meet the want, on account of their antiquity, they having been written some thirty years ago; hence their methods. Apparatus, etc., are not suited to the assayers of to-day. Others are either more suit able as books of reference, or do not give sufficient detail for the inexperienced. It is this latter fault I have carefully endeavored to avoid, and perhaps have gone to the other extreme. At all events, I have tried to give here in print the precise instruction which I have previously imparted orally to my students. Those who may choose to criticise, will remember for whom this hand book it} written. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
