Excerpt from The Flotation Process
This book has been prepared to meet the need of the hour. Flota tion is engaging the attention of a rapidly increasing number of metallurgists, mill-men, and mine-owners. Information on the subject is lat-king. The. Only book heretofore issued was written four years ago, and is now out of date. In 1912 the flotation process had hardly won a foothold in the United States; today fully tons of ore is being treated daily by the frothing or bubble-levitation method. In July 1915 the Mining and Scientific Press began to publish a series of articles describing current progress in this new branch of metallurgy. These were followed by a number of interesting contributions on the theory of the subject. All of them are reproduced in this volume. They claim no finality. The physics of flotation is still a riddle nu solved; but the beginnings of investigation have been made. In the pages that follow will be found the rudiments of a connected theory explaining the phenomena underlying the life and activity of the metallurgic bubble.

Paperback. Zustand: New. Print on Demand. This book delves into the fascinating world of flotation, a revolutionary process that revolutionized mineral extraction in the early 20th century. The author, a keen observer of the industry, takes the reader on a journey through the history of flotation, meticulously tracing its evolution from early, often haphazard attempts to separate valuable minerals from ore, to the emergence of more sophisticated and scientifically-grounded methods. The book explores the fundamental physical principles behind flotation, focusing on the key role of surface tension and the creation of bubbles. The author meticulously dissects the role of oil, acid, and air in facilitating the separation of metallic sulfides from the surrounding gangue. The reader is guided through a detailed exploration of the various methods developed and applied in the early years of the 20th century, from the bulk-oil method of the Elmore brothers to the more refined frothing methods pioneered by Minerals Separation. Through a careful examination of patents and historical accounts, the author reveals the ingenuity and sometimes serendipitous discoveries that led to the development of flotation. The book provides a fascinating glimpse into the scientific and industrial landscape of an era marked by both innovation and competition, revealing the complex interplay between scientific understanding, practical application, and commercial interests that ultimately shaped the future of mineral extraction. The book's insights into the early development of flotation offer a valuable historical record of this pivotal advancement in mining technology.
