Once in liquid form, the gold and silver are subjected to liquid-solid separation process in the thickener tank. This system is also called counter current decantation. Flocculant (precipitator) is added to the tanks in this unit, allowing the solids to settle, after which it is sent to the detox unit, while the loaded upper current is sent to the recovery unit.

The process design of gold leaching and carbon-in-pulp
2009-8-27 concentration of gold in the aqueous phase is typically between 0.001 and 0.02 ppm with a value of 0.01–0.005 ppm regarded as a practically achievable value for most well-designed and operated plants. This represents a gold recovery of 90–99% depending on the tenor of the feed solution. These high recoveries are achieved because the carbon is

2005-1-1 In the case of gold, gravity tools can be useful in solving a number of problems. These can include what is termed spotty or coarse gold, which makes mass balancing and gold accounting extremely difficult. By utilizing gravity ahead of the leach train, early recovery of gold in the process can also have financial benefits and avoid potential losses.
