Paperback. Etat : New. Print on Demand. This book explores mining and milling practices in the Wisconsin district through a detailed analysis of one of the longest running and significant lead and zinc mining operations in the US. The author's exploration of the history and contemporary practices of lead and zinc mining in the district provides a rich historical backdrop against which the human ingenuity and industrial development of the time becomes apparent. The author does more than simply chronicle the technical details of mining and milling, though. He also discusses the social and economic conditions under which miners in the district worked and lived, which serve to humanize the tale of this region's industrial history. Anyone with an interest in mining history, the history of labor in the US, or the industrial practices of the late 19th and early 20th centuries will find this book insightful.

Paperback. Etat : New. Print on Demand. This book explores the innovative use of differential flotation for the separation and concentration of lead and zinc minerals in ores from the Coeur d'Alene region. The author, a notable figure in the mining industry, provides a comprehensive analysis of flotation as a viable alternative to traditional gravity concentration techniques. The volume presents a careful examination of various ores from the region, including screen analyses, microscopic studies, and detailed descriptions of the mineralogical assemblages found within each sample. Flotation testing, conducted with mechanical-agitation machines using dry-crushed ore, forms a significant part of the work. The author discusses the operating conditions, chemical reagents, and oil mixtures employed in these tests, with particular attention to the differential selection of lead and zinc minerals. The results, presented in tabular form, demonstrate the effectiveness of differential flotation in achieving high recoveries and good-quality concentrates. This book serves as a valuable resource for mining engineers, mineral processors, and researchers interested in the application of differential flotation techniques to complex lead-zinc ores.
