Ebook: Cyanide processes

Fourth edition, John Wiley & Sons, New York - Chapman & Hall, Ltd., London, 1908. - 249 p.
Good quality ClearScan.Owing to the recent improvements in cyanide practice, especially in the treatment of slime, the author
adds a chapter giving the latest treatment, thus bringing the fourth edition up to date.
Since the first edition, the volume of literature on the subject of cyaniding has increased twelve-fold (one fold for each year), and while many theories have been proved and disproved, there remains much to learn, although the process is an established metallurgical one.Contents
