· 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.
