GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.

In some deposits, gold and silver are sparingly substituted for copper in the ore, making these precious metals a valuable side product that in some cases can actually pay for the entire cost of extraction of all the copper. Extraction in open-pit mines begins with typical hard-rock mining methods, like blasting.
