The collecting agent bonds to the gold, creating an oily film that will later attach itself to the surface of air bubbles. The organic chemicals prevent the gold from bonding to other material. Air is then passed through the solution and the gold-laden film attaches itself to the bubbles. The bubbles rise to the top and the gold is skimmed off.

The major ores of gold contain gold in its native form and are both exogenetic (formed at the Earth's surface) and endogenetic (formed within the Earth). The best-known of the exogenetic ores is alluvial gold. Alluvial gold refers to gold found in riverbeds, streambeds, and floodplains.It is invariably elemental gold and usually made up of very fine particles.

Luckily, the gold contained in refractory ores is not unsalvageable. Gold's resistance to oxidation is a critical point of most refining and extraction methods, and the roasting process is no exception. During roasting, refractory gold ore is treated with extremely hot air. This causes the sulfites to oxidize, separate from the ore, and ...
