CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.
the South African underground gold mining industry, small changes in recovery and efficiency have a significant value over the life ... plant and/or full-scale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming ... The carbon-in-leach (CIL) process, illustrated in Figure 3 is a
The Basics of Small-Scale Heap Leaching with Cyanide. August 2007 by Chris Ralph. In last month’s article I talked a bit about opportunities for heap leaching small hardrock deposits. This month I’m going to talk about the basics of putting together a heap leach project, including building the pad and leaching the ore.

Small Scale . Carbon in Pulp extraction plants. 20/40 and 50/60 tons per day Units Preamble. The concept of the small-scale agitated leach unit was to design and build an agitated leach system for the small-scale mining industry, with a capacity equivalent to most small operations of around 20 to 40 ton per day.
Gold Carbon In Leach Plants Updated January 2017. Gold Processing Plant, Carbon In Leach (CIL) Plant. A Carbon In Leach Gold Recovery Plant. This plant processes 4 million tons of ore per year with an average gold content of 0.043 ounces of gold per ton of ore. Approximately 85% of the gold is recovered in the plant.
The carbon in pulp (CIP) and carbon in leach (CIL) processes became firmly established in the gold mining industry in the 1980s, initially in South Africa and Australia, from where they spread rapidly to all the gold producing regions of the world.

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.

CIP And CIL Mining And Minerals Industries . Carbon-in leach cil is a simultaneous leach and absorption process.The simultaneous leach and absorption phases of the cil process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon.These reduce the gold yield by attracting gold meant for the activated carbon.
