How Is Gold Extracted From Gold Ore?
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.

Gold CIL & CIP Gold Leaching Process Explained CCD
Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...

As it was shown in Table 2, Cu content of the ores varies from 1.47% to 16.30%. Hence, the collector dosage for the copper flotation was added according to their copper contents. Ores divided into three groups according to their copper contents and the collector dosages added accordingly at 30, 60 and 90 g/t (Bicak, 2011).
