Cyaniding Gold and Silver Ores

Abstract

THE cyanide process is still in its teens, but it is a lusty stripling. Much of the enormous increase in the production of gold during the last few years is due to it, either directly or indirectly. There are few gold mines of any importance in the world at which the process is not installed, and it has been stated on high authority that the majority of these mines could not earn profits and pay dividends without its aid. Owing to the shortness of the time since the industry of cyaniding gold and silver ores began to spring up, there is a lack of data on the subject readily available to men at work far from centres of civilisation. There are many books on the cyanide process, but new ones are still welcome, particularly a work like that of Messrs. Julian and Smart, in which some degree of completeness is attained. Cyaniding Gold and Silver Ores. A Practical Treatise on the Cyanide Process; embracing Technical and Commercial Investigations, the Chemistry in Theory and in Practice, Methods of Working and the Costs, Design and Construction of the Plant and the Costs. By H. Forbes Julian and Edgar Smart. Pp. xx + 405; illustrated. (London: C. Griffin and Co., Ltd., 1904.) Price 21s. net.
