Sinopsis
Practical guidance on flotation for ore concentration, from lab tests to full-scale plant methods.
A Manual of Flotation Processes presents the essential facts behind flotation, describes key apparatus and testing methods, and shares generalizations drawn from mill practice. The book helps engineers translate laboratory results into commercial operation, with a focus on the different flotation routes, control variables, and practical considerations in real mills.
- How flotation is defined and the main process types used to separate concentrates from tailings
- What equipment and testing methods are used in laboratory and pilot scales
- How ore amenability, grinding, and flow sheets influence flotation results
Ideal for students and professionals who want a clear, actionable overview of flotation theory and practice in ore dressing.

Excerpt from A Manual of Flotation Processes
Flotation, as the term is applied to ore concentration, means the separation of one of the constituents of an ore from the remainder by causing it to float at or above the surface of a pulp consisting of the finely pulverized ore and water.
Minerals that float have a metallic, adamantine, or resinous luster. Minerals with vitreous, pearly, or earthy luster do not float, as the term is at present used in the art of concentration. It must not be understood, however, that the float concentrate in a flotation operation is free from these latter minerals. As a matter of fact, in many flotation concentrates the minerals of non-metallic luster predominate. Their inclusion is due in part to their being mechanically entrapped and held, as on a screen, by the bubbles composing the froth, in part to the inclusion of pulp in thick bubble walls, and in part to the removal of some of the pulp, as such, with the floating concentrate.
Ores amenable to concentration by flotation. Almost any ore consisting of a mineral of metallic, resinous, or adamantine luster associated with the usual rock-forming minerals, can be concentrated by flotation. In the great majority of cases the part of the ore that floats is the valuable portion D but if the constitution of an ore were such that the valuable mineral had a non-metallic luster, and the gangue a metallic luster, the floated portion would constitute the tailing while the valuable portion would remain submerged and be drawn off as residual pulp.

Excerpt from A Manual of Flotation Processes
Flotation concentration includes within its scope almost as many processes as all other methods of ore concentration combined, the only elements common to all the processes being selection, or concentration, and separation of the concentrate from the tailing by flotation of the former.
Widespread understanding of the physical principles underlying flotation phenomena and of the diversity of flotation processes has been delayed for divers reasons. The apparent complexity of the phenomena and the difficulties of investigation are sufficient to explain some of the delay, but much of it is chargeable to the stand of patent-owning corporations in their attempt to establish a monopoly on flotation processes. These companies have steadfastly opposed dissemination of knowledge of the art by their employees and licensees, notwithstanding the moral and legal duty of a patentee to make full and truthful disclosure of all he knows concerning the subject matter of his patent; by threats of litigation sown broadcast they have succeeded in causing a veil of secrecy to surround the operations of non-licensees; and by their unfounded claims that all flotation processes prior to that described in U.S. Patent 835, 120 were laboratory curiosities or commercial failures, and that those subsequently discovered were merely improvements of that process, they have caused the spread of wrong ideas on the part of many of those interested.

Paperback. Condición: New. Print on Demand. This book delves into the fascinating world of flotation concentration, a process that revolutionized ore extraction in the early 20th century. The author, a pioneer in the field, guides readers through the various methods of flotation, from the earliest skin flotation techniques to the more advanced froth flotation processes. The book explores the intricate workings of these methods, revealing the interplay of forces like surface tension, oil adhesion, and gas supersaturation that determine the separation of valuable minerals from their surrounding rock. The author takes readers behind the scenes of laboratory experiments and industrial-scale operations, highlighting the importance of careful testing and precise control over variables such as grinding fineness, oil selection, and pulp density. He also delves into the complexities of differential flotation, which seeks to isolate specific mineral types from a mixture, and the challenges of effectively processing oxidized ores. The book ultimately aims to dispel common misconceptions surrounding flotation, providing a comprehensive and detailed understanding of this crucial technology, and its role in the evolution of mining practices. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
