Gold Agitation Cyanidation Leaching. Oct 18, 2019 The agitation leaching method is to concentrate the slurry, obtained after grinding and classifying of the goldcontaining ore, to a suitable concentration, place it in a leaching tank, add a cyanide solution, and aerate to carry out leaching The main equipment used in the agitation leaching process is a …
OKTOP® CIL reactors are specially designed and optimized equipment for the gold cyanide leaching and recovery, and are suitable for both CIL and CIP process applications.
The N°4 leaching agitator tank discharges, by gravity, to a battery of 6 agitator tanks, 12'x15', which contain activated carbon for the recovery of the gold dissolved in the pulp in a proportion of 57 Kg/m³.
The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation in which the leach tanks are fitted with carbon retention screens and the carbon-in-pulp tanks are eliminated. The activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with gold dissolution by the cyanide ...

Carbon Screens In Cyanide Agitator Tanks. The process design of gold leaching and carboninpulp saimm Although air agitated leach tanks were commonly used in reactor by means of screens having an aperture of 06–08 contacting the carbon with a solution of sodium cyanide reduced, as only one set of agitators for both leaching andCone …
The slurry may also be subject to other preconditioning such as pre-oxidation at the head of the circuit before cyanide is added. Highly activated carbon is used in the dissolved gold and/or silver recovery process, either by introducing it directly into the CIL (carbon-in-leach) tanks or into separate CIP (carbon-in-pulp) tanks after leaching.
In CIL, adsorption of gold and silver onto activated carbon is also completed in agitated tanks with interstage screens used to retain the activated carbon within the tank. The …
A typical CIL plant consists of six to eight tanks of about 2500 m3 to 3500 m3 in volume. Each tank contains a carbon transfer pump, an intertank screen and an agitator. The carbon transfer pump transfers carbon from one tank to another. The intertank screen prevents carbon movement from one tank to
Cyanide Training Proper care and handling of Sodium Cyanide. ... Add the NaCN to the NaCN mixing tank continuously, until the whole reagent is discharged into the mixing tank ... Do not use carbon dioxide extinguishers or extinguishers that may contain acidic compounds; Spills involving Cyanide in solid form. AVOID over reaction;

For solution customers, Cyanco delivers sodium cyanide in liquid tank trucks that offload directly into on-site storage tanks. At Cyanco, our drivers ONLY drive sodium cyanide trucks, custom engineered for the safe transport of solution cyanide.
The discharge of the first tank is gravity fed into the second tank where the cyanide is added at a dosage of 300 ... tanks and agitators. Approximately 50% of the total gold processed by the plant gold is dissolved and recovered onto the carbon. ... The collected slurry is then pulled out of the tank and poured onto a screen to collect the ...

The cyanide pulp enters the stirring adsorption tank (carbon slurry tank). Add carbon to the leaching tank, and the carbon adsorbs the gold in the pulp to become gold-loaded carbon. After the adsorption is completed, the carbon and the pulp are separated by a carbon extraction screen.
From the splitter box, slurry flows to six C.I.L. tanks sized to provide a total of 16 hours of retention time. Each C.I.L. tank has an agitator and two Kemix screens for carbon retention. Slurry discharging from the last C.I.L. tank passes vibrating carbon safety screens and is then treated with A.B.S. for cyanide destruction.
The loading of gold cyanide onto activated carbon is a reversible reaction, and therefore the amount of gold on the carbon in any CIP tank affects the rate of adsorption of gold onto that carbon. This effect is most critical in the last CIP adsorption stage, because any gold that is not extracted there is lost to the tailings.
The introduction of activated carbon to recover gold from cyanide leach solutions in the last quarter of the 20th century had a similar impact on the economics of gold ore processing. ... elimination of carbon back-mixing due to carbon not being transferred as a batch in cascade CIP; ... Regenerated carbon is added to the last tank …
The activated carbon from the second set of agitators is raised to a carbon screen to obtain gold-loaded carbon, and the remaining slurry is returned to the first set of …
The carbon slurry process (CIP) is one of the gold ore treatment processes and a cyanide gold extraction process. The full name is the all-mud cyanide carbon slurry process for gold extraction. The process of adsorbing gold cyanide complexes is often used for the flotation of gold concentrate or mercury amalgamation, gravity separation of tailings, …
The slurry is first aerated without cyanide present to minimize the cyanide consumption (pre-aeration). It then flows into the CIL, (Carbon-In-Leach), tanks where cyanide, oxygen and activated carbon are added. The oxygen and cyanide dissolve the gold, which is then absorbed onto the activated carbon.
The jets consist of ¼ pipe, running from a 1″ header, equally spaced around the circumference of the agitator tank and projecting 10′ under the surface of the pulp. ... the many streams of pulp passing through the screen are thrown across the tank in very small particles. ... is fed with ore, cyanide, lime, and carbon as charcoal. The ...
a. Impermeable secondary containment for cyanide unloading, storage, mixing and process tanks shall be sized to hold a volume at least 110% of the largest tank within the containment and any piping draining back to the tank, and with additional capacity for the design storm event; and b.
The stirring tank is used for stirring the slurry and mixing chemicals to ensure uniform and efficient cyanide leaching. The adsorption tank is the main place where activated carbon adsorbs gold ions.

Carbon in Leach vs Carbon in Pulp: Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution.
Agitation was superb resulting in rapid dissolution and effective washing of the carbon off the horizontal carbon screens. In conclusion, the triangular agitator is far superior to …
