Leach considerably slower in cyanide adams, 2000. as a result of cyanide soluble copper in the ore, cyanidation of goldcopper ores results in high cyanide consumptions and difficulty in process control. the gold leaching reaction in cyanide solution follows these electrochemical halfreactions
Heap leaching is being done worldwide on relatively low-grade ores for copper , gold and uranium recovery. typical operations take place from piriods of 2 months to 6 months per heap, and the recovery achieved is higher then 50 and may get as high as 80 in some cases.
Required for gold leaching by cyanidation. another example of chemical interference is the presence of graphitic carbon in a gold ore. this species, which occurs naturally in many orebodies, particularly in the sw united states and west africa, is able to re-adsorb gold cyanide from the leach solution, lowering overall gold recovery.
Apr 01, 2014nbsp0183321. introduction. cyanide leaching has been the predominant process for gold extraction from mineral resources for more than a century hilson and monhemius, 2006, li et al., 2012b, 214rg252l and atalay, 2002.the major reasons for the acceptance of cyanide over the other lixiviants include higher chemical stability, lower cost and better understood chemistry ofori-sarpong and osseo-asare, 2013.

Nov 19, 2009nbsp018332q. sir, i am doing the scrap gold. i got a problem in gold recovery that is, actually i am using the method of collecting the gold coated material and adding the nitric acid and giving the heat. after boiling the acid, the gold layer appearing the top, collecting the gold layer, when i try to heat that gold it becomes nothing.
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 ...
