Carbon in Pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.
Activated carbon acts like a sponge to aurocyanide and other complex ions in solution. Hard carbon particles (much larger than the ore particle sizes) can be mixed with the ore and cyanide solution mixture. The gold cyanide complex is adsorbed onto the carbon until it comes to an equilibrium with the gold in solution. Because the carbon particles are much larger than the ore particles, the coarse carbon can then be separated from theslurry by screening using a wire mesh.
CIL gold extraction machine consists of following steps:
1 The ore is first reduced in size (typically 80% passing 200mesh ) to ensure that all nonrefractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold
industry, such as: Multi-stage crushing, then ball milling circuits, typical of ball mill and hyrocyclones.
2 Thickening(add lime flocculant)
After comminution the pump is normally dilute and thickening. High efficient thickener is performed to increase the pulp density to about 50% solids by mass.
3 Leaching
Leaching reagents in the form of cyanide and and oxidant such as air or oxygen are added after thickening. Leaching take place in a series of agitated leaching reactors.
4 Carbon adsorption
After leaching, the pulp is passed over a feed screen to ensure removal of tramp materials about 0.6mm. This is done to minimize screen blocking in the adsorption section. After feed pre-screening, the pulp flows trough a cascade of well mixed adsorption tanks, typically 6-8 in number. The pulp residence time is about one hour in each tank. The tanks are normally mechanically agitated and each will contain a batch of carbon of concentration 10-25grams of carbon per litr of pulp. The carbon size is 0.6-0.8mm. The gold recovery is 90-99%.
5 Desorption and electro-winning
The loaded carbon is processed by desorption and electro-winning set, by this solution, it gets grain gold.
6 Gold melting
