Book Description
Excerpt from Concentration by Flotation He had the germ of an idea pregnant with metallurgic possibility, but it was still-born. Haynes and Bradford had inklings of the phys! Ical phenomena underlying the flotation process, but they were pio neers that blazed no trail and crossed no range of fruitful discovery. Carrie J. Everson comes next in point of time. Her groping after a practical process is noteworthy by reason of the introduction of acid, but her trail also stopped at the foot of the talus on the slope of the range. The patent records disclose other abortive attempts in the same direction during the ensuing decade, but none is of any con sequence except H. L. Sulman's British patent of 1893, in which he describes a means for saving 'float' gold by adding something to the mill-water that will diminish its surface-tension. This is interesting as recording scientific curiosity concerning the physics of flotation on the part of a metallurgist that was destined to contribute so greatly to the decisive development of the process. His successful participation is due, in part, to his having been formerly engaged professionally in the chemistry of the oil and soap industries, for thereby he acquired knowledge of a kind that proved of great value to him at a later date. So far no workable method had been invented - only ingenious schemes and impracticable proposals. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
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.

Book Description
Excerpt from Certain Interfacial Tension Equilibria Important in Flotation Some idea of the tremendous importance of flotation as an indus trial process is obtained from the fact that in 1918 it was utilized in treating some 70 million tons of ore.1 However, although this proc ess profoundly influences modern practice in ore concentration, knowledge regarding it is largely empirical. 'for this reason writers have studied some of the principles often mentioned in the literature. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
