The experimental work which comprises the subject matter of this- thesis was carried out in the Metallurgicel and Ore Dressing Laboratories at McGill University. A flotation concentrate from the Beattie Mine, received at the University in the fall of 1936 was used. At the time the treatment of the ore at this property consisted of direct cyanidation followed by flotation, the flotation concentrate being shipped by rail and water to the Tacoma Smelter of the American Refining and Smelting Co. Ltd. Since the investigation concerns itself with the extraction of gold from arsenical ores by the cyanide process, a short history of the development of the cyanide process is included, as well as a summary of previous work treating arsenic ores. A review of the modern concept of the mechanism of gold solution is also included.
