A review of the flotation of native gold and electrum
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.

A systematic review of sustainable gold extraction from raw
Gold flotation is widely used in the case of refractory ores, in which small-sized gold particles, locked within sulfide minerals, are recovered through flotation of gold-bearing minerals (Marsden and House, 2006). It is also an effective means for separating free gold from silicate particles present in ore.
