Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Flotation Tests of Idaho Ores In view of the fact that it has been difficult to obtain representative samples of flotation feed from the mills, owing to the necessity of shipping the material wet and free from oil or other foreign matter that might be deleterious to the differential separation of the sul phides, the writers have felt justified in running flotation tests with the mill feeds in order to ascertain whether a differential separation of the sulphides could be effected. However, two different lots of flotation feed were tested for differential flotation, and the results of tests of one of these are given in this report. It is hoped that it will be possible later to test out the flotation feed for differential flota tion oni'a large scale in some of the mills. This paper covers part of the investigations carried on by the United States Bureau of Mines in cooperation with the Idaho Bureau of Mines, the University of Idaho, and certain mining companies of the Coeur d'alene region. Although the results of the tests included in this report are not to be considered final, they indicate possibili ties and may suggest others leading to a solution of the problem of separating lead and zinc sulphides by differential flotation in the treatment of certain ores.

Book excerpt: Excerpt from Answer to Questions of the Flotation of Ores As far as can be learned the difference between the two froths lies largely in the different percentages of air and moisture as compared to the amount of solids; The continual supply of air by the pneu matic method produces a condition under which each rising bubble carries only a few grains of mineral, whereas in the mechanical methods the bubbles come up fairly heavily laden.

Available in PDF, EPUB and Kindle. Book excerpt: 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 Only book heretofore issued was written four years ago, and is now out of date.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.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Concentrating Ores by Flotation: Being a Description and History of a Recent Metallurgical Development, Together With a Summary of Patents and Litigation This book is intended as an interim report of progress in a rapidly developing art. It is put forward in the hope that it may prevent duplication of labour on the part of ambitious inventors, and that it may give engineers not already familiar with the subject a starting point in the application of a new method of turning ores to account. My debt to the labour and assistance of others can hardly be acknowledged adequately. To the directors of Minerals Separation, Ltd., cordial thanks are due for permission to publish much information collected during four years while acting as their general manager and consulting engineer. Although this permission is kindly granted, they are not necessarily in agreement with all the opinions expressed, and, in fact, quite properly oppose some of the views set forth. To H. Livingstone Sulman and Hugh F. K. Picard, of the firm of Sulman Picard, I am indebted for many ideas absorbed from them through three years of pleasant professional association (during which time the were consulting metallurgists to the above company). They have in preparation a book on the 'Theories of Concentration Processes Involving Surface Tension, ' which will be a work of high scientific merit. I have endeavoured, I hope successfully, not to trespass on any new and unpublished ground, the announcement of which rightfully belongs to them; further, it is not my desire to present the subject in so profound a manner as they will do, deeming it of considerably more use to engineers to leave the discussion of the mathematical and physical laws involved for another occasion.

Howard Higgins, George A. Chapman, A. Sydney Stevens, E. Ray Wilkinson, Alfred K. Burn. A. C. Howard, George C. Klug, C. J. Hylton, John Leechman, F. Glynn Price, and E. E. Wood, I am indebted to an extent that the mere mention of their names but scantily requites. The files of the current technical journals and financial papers have been drawn upon with a free hand; these receive individual acknowledgment in the bibliography.

The mill handles tons of sulphide ore monthly. The vanner tailings are reground for otation. In a 9-cell Minerals Separation machine, the feed to which averages per cent copper and pennyweight gold per ton. The monthly recovery is tons of concentrate, averaging 8 to 9 per cent copper and 5 pennyweight gold per ton, the recovery being 86 per cent of the copper and 43 per cent of the gold. The total extraction in the mill is 80 per cent of the gold and 90 per cent of the copper. This is the first large-scale otation plant at work in South Africa.
