Native gold and electrum are naturally-occurring alloys containing gold and silver and a little copper. They are the most common and important forms of gold in ores. Their recovery by gravity concentration, cyanidation, or flotation from ores, typically containing 0.1–20 g/t Au is of great commercial importance.

Jan 24, 2014 The gold does not stay attached to the bubble in the froth of a flotation cell. Flotation as a method of recovering metallic gold is a poor way to go. Flotation works great as way to recover sulfides, including sulfides that have microscopic gold encased in them, but it does not work for recovering fine, free gold.
FLOTATION Flotation is the most widely used mineral separation method. It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are processed by flotation annually. The underlying principles of the flotation process are well established but it has proved to be
Flotation is widely used to concentrate copper, lead, zinc, iron and even gold and silver minerals, which commonly accompany one another in their ores. Many complex ores formerly of little value have become major sources of certain metals by means of the flotation process.
The first countercurrent column flotation device was designed and tested by Town and Flynn in 1919. Cross-current pneumatic flotation machines were widely used in industry in 1920’s and 1930’s, but were later replaced by the impeller-type flotation devices in mineral processing plants.
