3. Carbon-In-Leach CIL The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. 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.

developed. The effect of leaching parameters on gold cyanidation is studied in this work in order to optimize the leaching process. A gold leaching model, based on the well-known shrinking-core model, is presented in this work. It is proposed that the reaction takes
In CIL carbon in leach process, activated carbon acts like a sponge to aurocyanide and other complex ions in solution. Hard carbon particles much larger than the ore particle sizes can be mixed with the ore and cyanide solution mixture. The gold cyanide complex is adsorbed onto the carbon until it comes to an equilibrium with the gold in ...

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
process the first way is to use a production technology, which does not utilize an external carbon-bearing source as a carbon donor, or one that would not generate CO 2 as a by-product in the process the second option is to use carbon-bearing fuelraw materials and captureremove CO 2 emitting from the downstream side of process.
CIL Carbon In Leach leaching process, that is, carbon leaching gold extraction, is a process of adding activated carbon to the pulp and leaching and adsorbing gold at the same time, which simplifies the CIP Carbon In Pulp process The two steps of leaching pulp and activated carbon adsorption are one step, which reduces management costs while reducing losses.
that are packed with carbon. The process is known as carbon-in-columns CIC. For mill, agitated-tank leaching operations, gold is extracted directly from the leached pulp in either a carbon-in-leach CIL, or a carbon-in-pulp CIP plant. In both these cases, the coarse granules of activated carbon are mechanically mixed with the
