the gold cyanidation process is the most important method ever developed for extracting gold from its ores. the reasons the widespread acceptance of cyanidation are economic as well as metallurgical. it usually obtains a higher recovery of gold than plate amalgamation and is easier to operate than the chlorine or bromine process.
gold cil and cip gold leaching process explained ccd. 2 nov 2018 . carbon in pulp cip is the sequential leach then absorption of gold from ore. . these reduce the gold yield by attracting gold meant for the . during leaching to remove high grade gold solutions, and re diluting the .
a free milling gold ore, which contains 0.4% copper as chalcopyrite, was treated with cyanide. in the pre-leaching, the kinetics of oxidation of soluble sulphides are not an accurate indication for the length of the treatment.
a bullion of high fineness in the region of 98% gold and silver was obtained and the activity of carbon after elution was reasonably high at 8 0% of carbon. one detrimental effect of the changes made to improve the gold recovery was a high residual cyanide content in the cip tails. this was overcome by the use of the inco process at a

cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. the gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. cil stands for carbon-in-leach. this is a gold extraction process called cyanidation where carbon is added to
