It was describe by the use of 600 series of flotation reagents which were developed primarily for the purpose of depressing carbonaceous and siliceous slimes in the flotation of gold ores. Carbonaceous material not only greatly increases the bulk and moisture content of a flotation concentrate, but its presence makes cyanidation of the concentrate difficult or impossible owing to reprecipitation of the gold during treatment.
Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the golds hydrophobicity. This mixture is placed into a large tank filled with distilled water.
The flotation method is a widely used technique for the recovery of gold from gold containing copper ores, base metal ores, copper nickel ores, platinum group ores and many other ores where other processes are not applicable.

The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the golds hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water. Air bubbles are pumped into the flotation cell and the water is agitated.
grade copper gold ores from open pit and underground sources in two parallel processing trains. The copper flotation circuits upgrade copper content by a factor of 80 160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed (remaining gold is recovered
R. Dunne, in Gold Ore Processing , 2016 6.2 Depression of Sulfide Minerals With Cyanide The depressing action of cyanide on pyrite during froth flotation is well known and is widely exploited on many flotation plants to selectively separate copper minerals from pyrite.
