This is not a book for the casual reader, although any one who even glanced at the cover would probably be able to discern this! It does a very thorough job of informing the reader about how mining for precious metals was done, right from the prospecting through digging, blasting, tunneling, removing the ore, milling and finally preparing the metal for shipment. There is also some history about different famous mines in the American West and of the various gold and silver rushes and the people who were drawn to them. The book has a more technical bent to it, but the author never lapses into an academic style; he seeks to not only inform but entertain. The book is not intended to be comprehensive regarding mining equipment nor techniques, but upon completion the reader will have a general understanding of precious metal mining in both history and method.

Here, for the first time, is a clear account in words and pictures of the methods by which gold and silver were extracted and processed in the Old West. The author describes the early days of Spanish and Indian mining and the wild era inaugurated by the American prospector who rushed west to get rich quick, ending with the year 1893, when repeal of the Sherman Silver Purchase Act virtually closed the mining frontier. The account gives in laymen?s language the techniques employed in prospecting, placering, lode mining, and milling, particularly those employed by the Spaniards, Indians, and Cornishmen, and shows how the ever-practical Americans adapted and improved them. Special attention is given to the methods employed in the California and Montana gold fields, Colorado and the Comstock Lode, the Black Hills, and Tombstone, Arizona. In these pages the reader also meets some of the unforgettable personalities whose lives enriched (and sometimes impoverished) the mining camps. Não foram encontradas descrições de bibliotecas. |
