· Cyanide leaching gold ore. 083120; 243 Views; icon 1; Cyanide leaching gold ore . There are four points to pay attention to when leaching gold ore with cyanide: slurry concentration, temperature, cyanide and oxygen concentration, protective alkali, etc.
Sodium cyanide, slaked lime slurry and air are added into the tanks. The slurry ﬂws from tank to tank by gravity and gold is leached into the solution by cyanide and oxygen. Lime is added to the leach circuit to maintain a high pH of the slurry. This minimizes the formation of hydrogen cyanide. 2. Carbon adsorption

Carbon Adsorption In Recovery Of Gold. From Cyanide Leach Solutions. It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject. Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until ...
· Sodium cyanide is the most commonly used leaching chemical in gold extraction process. According to theoretical calculation, leaching 1 gram of gold only requires grams of sodium cyanide. However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50100 times higher than the theoretical calculation.
The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metalimpregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted. Vat (or tank) leaching: The ore is mixed with cyanide solution in large

Gold By Cyanidation Leaching Tank. Extraction of gold by using a tank leaching systems typically use a lot of multiple tanks in series within a building Different from heap leaching are loed at the open air Gold leaching process carried out by stirring the gold ore is mixed with limestone and added with a solution of cyanide in a tank.
· Cyanide leaching. After the crushing and grinding stage of the CIL gold mine process, the slurry is added to 9 highefficiency cyanide leaching tanks arranged in steps. The first 2 gold ore slurry is cyanided first, and the last 67 leaching tanks Activated carbon is added while cyanidation is performed for countercurrent adsorption operation.

cyanidation process, granular activated carbon is added to the leached slurry. The carbon adsorbs the gold from the slurry solution and is removed from the slurry by coarse screening. In practice, this is accomplished by a series of five or six agitated tanks where carbon and ore slurry are contacted in a staged countercurrent manner.
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 ...

The drive system consisting of motor, reducer and support base drives the agitator to rotate. The agitator has the lower and upper impellers, each with four blades.
If there is no releachable gold at the end of circuit you can drop the cyanide target in the first tank but if you still have releachable gold you have to investigate why this not leaching . You may need to check the pH if it is suitable for your circuit or need to adjust it or may be something else.
