Following this procedure, a stream of air bubbles is passed through the pulp; the bubbles attach to, and levitate, the hydrophobic particles, which collect in a froth layer that disengages from the flotation cell by flowing over the weir of the cell. A frother, such as a long chain alkyl alcohol, is added to create a stable froth layer in the cell.

Silver and gold are extracted by the cyanide process (Mac Arthur - Forrest process). After the preliminary crushing and concentration by froth floatation process, the ore (crushed auriferous rocks in the case of gold) is leached with dilute (0.4 - 7%) solution of sodium cyanide made alkaline by adding lime kept agitated by a current of air.

Silver is removed by the Parkes process, which consists of adding zinc to the molten lead bullion. Zinc reacts rapidly and completely with gold and silver, forming very insoluble compounds that float to the top of the bullion. These are skimmed off and their zinc content recovered by vacuum retorting.
