In the cyanide baths, the carbonate can be formed by different ways, but can be formed mostly by absorption of carbon dioxide from the air (reactions 1A and 1B) or by hydrolysis of the cyanide. 2XCN + CO2 + H2O = X2CO3 + 2HCN (1A),X: Na or K 2XOH + CO2 = X2CO3 + H2O (1B),...

The loaded carbon leaving the first CIP tank will be transferred to the carbon stripping circuit, while the leach residue will be sent to a carbon safety screen to recover any coarse carbon grains. The screen undersize will report to the residue thickener prior to being pumped to the cyanide destruction circuit.

3、Leaching and adsorption : put the slurry after decontaminated and concentrated into the highefficiency leaching tank, there are 58 tanks normally, add cyanide solution into the former two tanks, add activated carbon into the other five tanks, activated carbon adsorb gold become the loaded gold carbon, the loaded gold carbon lift into the lifting screen by air lifter, the lifting screen separate .

tanks are used as preaeration agitator tanks wherein compressed air is injected and tanks are mechanically stirred in order to oxidize all the sulphide ions available in the slurry. A solution of sodium cyanide and sodium hydroxide is added in the fourth tank as

The tanks are normally mechanically agitated and each will contain a batch of activate carbon for adsorption (generally 1025grams of carbon per liter of pulp). The carbon size is The actual gold adsorption rate could reach 9599%.

Each CIL tank will have approximately 10 g/L of carbon. The carbon will beadvance d countercurrent to the pulp by air lifts. Loaded carbon from the first tank will be recovered over a loaded carbon screen and directed to the elution circuit. The pulp from the last CIL tank will be directed to cyanide detoxification.

Flo King is the fourinone, intank system that pumps, filters, agitates, and treats electroplating, anodizing, printed circuit, lowsludging iron phosphate, and allied metalfinishing solutions. The Flo King system offers many advantages, including: • The elimination of leaks and spills associated with outoftank filter systems.

The adsorption rate of gold is higher than that of conventional coconut carbon in cyanide leach solution. The loading gold can be easily desorbed as coconut carbon. Crushed fine magnetic carbon ...

CarbonInPulp (CIP) In CIP, the ore is crushed and finely ground, and cyanide leached in a series of agitated tanks to solubilise the gold. The granular activated carbon is added to the leached slurry, where the carbon adsorbs the gold from the slurry solution and is then removed from the slurry by coarse screening. Often a series...

This agitation tank series is used for the agitation, leaching and carbon adsorption in the gold cyanide plant with the particle size of 200 meshes more than 90% and the concentration of less than 45%.

Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution. The CIL process is frequently used when native carbon is present in the gold ore.

tanks where lime, cyanide and hydrogen peroxide are added to effect gold dissolution. Slurry from the leach circuit is then fed into a carbon adsorption train, via a tramp screening step, in between the two tank farms. Carbon is recovered upstream of the adsorption train and eluted through a .

Invitation closed Kumtor Gold Company (KGC) announces a prequalification selection process for the design, manufacturing, supply, construction, assembly and commissioning works for "CIL Tanks Installation at the Kumtor Mill" including purchasing of all required equipment according to the engineering calculations (agitator drive gearbox with the electric motor, agitator with impellers ...

The slurry will enter into 8 sets of double impeller leaching tank; wellmixed sodium cyanide agents are added to the first tank; active carbon is added to the tanks from the second to the eighth; active carbon from the second agitator is lifted to carbon screen to get goldloaded carbon, and after cleaning, the goldloaded carbon enters into the desorptionelectrolysis system; while the slurry left goes back to the .
