  • Modeling and optimization of Carbon in leach (CIL)

    Carbon in leach (CIL) is an important step in gold processing that involves simultaneous adsorption and leaching While the mechanism of leaching and adsorption are well known, the effect of different operating and design parameters on the dynamics and performance ofThe carboninleach process integrates leaching and carboninpulp into a single unit process operation in which the leach tanks are fitted with carbon retention screens and the carboninpulp tanks are eliminated The activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with gold dissolution by the cyanideCarbonInLeach | Jacobi CarbonsThis processing concept dates back to about 1752 when the Spanish miners percolated acid solutions through large heaps of oxide copper ore on the banks of the Rio Tinto River Since then, this process has been used extensively throughout the world to leach oxide copper values from mine strip material from open pit mining of porphyry copperHow to Process Gold Ores by Heap Leaching &
