New Book For Miners

Cyaniding For Gold, By Lon

Idriess. Published by Angus and Robert son, Ltd., Sydney, for 10/-.

Here is a book that will interest Pacific Islands goldminers. In simple language it explains the cyaniding process from A to Z—for the man who can only invest £2O in a plant up to the syndicate that can afford £3,000. This highly successful pro cess has hitherto been the almost exclu sive domain of the metallurgical chemist: now, this book brings it within reach of any man interested.

Cyaniding has meant the recovery of many millions of pounds, not only from

new mines, but from old abandoned dumps. Once understood, the process is simple and has proved its efficiency in extracting very low values in gold from ores, or abandoned sand or slime dumps, operating in big or huge tonnages, de pending upon the size of the plant.

Leaching plants for the treatment of sand, and agitator plants for slime treat ment are clearly described, and their op eration explained from the start to the smelting of the bullion.
