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.

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Extracting Gold HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to

Pregnant Solution Recovery Gekko

Resin columns, such as the G-REX, are good for treating flotation solutions or preg-robbing ores because they are simple to use, affordable and are not fouled by flotation chemicals. A carbon-in-solution process is best for treating high volume slurries, while zinc precipitation (Merrill Crowe) is great for high volume solutions.

Ion Exchange Australia

The ion exchange process includes three major stages: sorption of valuable or unwanted ions, desorption (or elution) and washing. An addition stage regeneration could be used in case when the IX resin needs to change a from after elution.
