Oct 25, 20150183;32;The CIL circuit includes leach and absorption tanks followed by a 4 tonne capacity pressure Zadra elution circuit. The plant also contains a hydrogen peroxide cyanide destruct circuit discharging to two tailings storage facilities.
The plant was designed to treat the three ore types in stages. Throughput was set to 4 Mtpa, due to Sukari ore being harder, at a head grade of 1.7 g/t to produce 200 000 oz of gold.
conditions, elution (desorption) of gold from the carbon occurs. The main factor that makes desorption or stripping a simple process is the fact that gold will only adsorb onto carbon at low temperatures.

At the Misima gold mine (Papua New Guinea), the ore grade was 1.5 g/t gold and 9.0 g/t silver which necessitated the use of six by ten tonne carbon stripping columns.
The use of this type of pump should make the continuous elution process competitive in smaller sized plants, possibly down to one tonne per day plants or smaller. A one tonne per day column would be approximately 300 mm diameter by 5 metres tall.

Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until the 1970's, with the explosion of heap leaching of vast quantities of low grade gold ores, and subsequent production of many gallons of pregnant leach solution.

The gold elution profiles at 130176;C and 700 kPag for the other two carbon samples, C1 acid washed, and C1 loaded were compared to the profiles for the C2 acid washed carbon, as shown in Figure 3.
Elution of gold from carbon by the Micron solvent distillation procedure. Hydrometallurgy, 14 151169. The desorption of gold from activated carbon is promoted by adding organic solvents to aqueous cyanide solutions. At 6580 the elution of gold is fast and is not affected by water quality.
Elution (Gold desorption) and Electrowining Carbon stripping in small mining scale is combined together with electro wining. The stripping column is divided into two parts, the bottom one is elution column and the top part is electro wining cell.

ELUTION OF GOLD FROM CARBON Gold cyanide at concentration used in CIP/CIL plants is physically and reversibly adsorbed onto activated carbon. Physical adsorption is a thermodynamically reversible process that can be reversed by disruption of the equilibrium between gold in solution and gold on the carbon.
AZMET can design any size desorption and recovery plant. Our current range of gold elution plants consist of carbon batch sizes ranging from 0.512 tonne. AZMET will however advise the client on the appropriate circuit selection, irrespective should the plant be containerised/ modular in design or a green
The 8T elution plant goldroom is based around Comos KIT plant design which provides for a two level structural goldroom with the lower floor accommodating the gold processing equipment and optional laboratory space, with a second floor dedicated to
