Book excerpt: Excerpt from Production and Properties of Zinc: A Treatise on the Occurrence and Distribution of Zinc Ore, the Commercial and Technical Conditions Affecting the Production of Spelter, Its Chemical and Physical Properties and Uses in the Arts, Together With a Historical and Statistical Review of the Ind This book was undertaken originally as the introductory portion of a treatise on the metallurgy of zinc. Upon the completion of the latter, however, it appeared advisable for various reasons to limit it to a consideration of the purely technical questions involved in the extraction of zinc from its ores, or rather the concentrated products which are delivered by the miners for smelting. Although a knowledge of the physical and chemical properties of the metal, the occurrence of its ores, and the conditions which affect the markets is of importance to the smelter, it is equally of importance to the miner and trader. It was thought therefore that a collection of the general commercial and technical data of the metal in a special treatise devoted solely to it would be useful to those who are engaged in the industry in the various ways, and with that in view the present book was prepared upon a considerable enlargement of the original plan. It has been the aim in this book to present a comprehensive review of the world's resources of zinc ore, the conditions under which it is produced, the concentration of the crude ore into a product suitable for smelting, and a summary of the statistics of the industry from the earliest records down to the present time. The extent into which the subjects of ore supply and mechanical concentration of the crude ore have been entered into is due to their especial interest in this industry. There is perhaps no other important branch of metallurgy in which the exigencies of the smelting process impose such narrow limits as to the grade and character of the ore and make the preliminary preparation of the ore a matter of such great concern as in the metallurgy of zinc. In concluding this preface, I desire to make acknowledgment to all who have aided me in the preparation of the book, and especially to Mr. E. C. Moxham for notes as to zinc mining in Virginia, and Professor H. O. Hofman for permission to reproduce illustrations from his valuable treatise on the Metallurgy of Lead; also to the American Metal Co. for its statistical publications, and the Robins Conveying Belt Co., the Wetherill Separating Co. and Mr. W. P. Cleveland for illustrations supplied by them. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
