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.
