Publisher's Synopsis
Excerpt from Concentrating Ores by Flotation: Being a Description and History of a Recent Metallurgical Development, Together With a Summary of Patents and Litigation
My debt to the labour and assistance of others can hardly be acknowledged adequately. To the directors of Minerals Separa tion, 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.
