no gold in solution and is therefore able to extract most of the remaining gold, bringing the total gold recovery (for both steps) up to 97%. A split system is used to achieve the highest possible gold grade in the final solution and also to minimise both electrowinning solution volume and potable water consumption. Elution Tanks

(2) A caustic/cyanide presoak may be used in a Zadra system. (3) A hot water wash is sometimes used at the end of a pressurized Zadra strip to gain some of the advantage of the water elution used in AARL stripping. (4) In situations where large amounts of copper load onto carbon with the gold and silver, a two stage strip may be beneficial.
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.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

commonly used in portable water treatment and waste water treatment. In the gold recovery industry, activated carbon from a number of precursors has been used. Due to the nature of the in-pulp process, the following characteristics are important: High affinity towards gold – kinetic activity and equilibrium loading.
Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material. Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than being deposited as metallic gold.
In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions.. In a liquid chromatography experiment, for example, an analyte is generally adsorbed, or "bound to", an adsorbent in a liquid chromatography column. The adsorbent, a solid phase (stationary phase ...
Gold and silver typically occur at very low concentrations in ores - less than 10 g/t or 0.001% (mass basis). At these concentrations the use of aqueous chemical (hydrometallurgical) extraction processes is the only economically viable method of extracting the gold and silver from the ore. Typical hydrometallurgical recovery involves a leaching step during which the metal is dissolved in an ...
This plant processes 4 million tons of ore per year with an average gold content of 0.043 ounces of gold per ton of ore. Approximately 85% of the gold is recovered in the plant. From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for the desired period of time.

Elution – A hot, concentrated cyanide solution pulls the gold from the carbon. Regeneration – A kiln reactivates carbon before the circuit reuses it. Electrowinning – Electricity passes through the gold-loaded (pregnant) solution, causing gold to form at a cathode, and cyanide at an anode. A smelter refines the gold. Carbon Fines Recovery
This causes gold to collect on the negative terminals. Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers ...
second hand gold elution tank The process design of gold leaching and carbon-in-pulp ... Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carbon-in-pulp circuit (CIP).

Gold from the pregnant thiourea solution is recovered by transferring the solution from the elution section to holding tanks for an electrowinning section. During electrowinning, the solution is circulated between the holding tanks and electrowinning cells. Residual gold on the stripped resin is expected to be below 100 g/t.
