The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was constructed.
The flotation method is a technique widely used for the recovery of gold from gold- containing copper ores, base metal ores, copper nickel ores, platinum group ores and many other ores where other processes are not applicable.
CIL (Carbon In Leach), the gold carbon leaching method, is the carbon leaching method for gold extraction.

Mined gold-bearing ore containing gold and silver is extracted and purified through a processing plant. In this gold recovery plant, the precious metals are extracted from the ore through a series of steps including: crushing and grinding; addition of process water (forming a slurry); cyanide leaching; floatation and vortex separation (cyclones).
C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery %. Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.
