Carbon in pulp

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 on carbon/gold in solution ratios of >1000:1 are achievable in many cases. The distribution of that carbon between the stages (within reason) is irrelevant. The concentration of carbon in the pulp varies with the size of the tanks, so it is irrelevant. Gold extraction efficiency is determined by:

Carbon In Pulp Literature Review

A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.

DYNAMIC SIMULATION OF THE CARBON

Activated carbon is then used to separate and store the gold, which is removed as the final step of the process. There are three basic operating systems in use for modern gold recovery: Carbon in Pulp: Carbon in pulp, or CIP, processing occurs when the leaching takes place in an agitation tank before the activated carbon is introduced.

Carbon Adsorption

activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurries. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carbon-in-pulp (CIP) and the carbon-in-leach (CIL) processes, have been widely used since the 1970s. Due to the economic

carbon in pulp process gold. Carbon-in-pulp The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or "pregnant" with gold.

How gold is made

Jan 01, 2016· By replacing the Merrill–Crowe zinc cementation step, carbon-in-pulp (CIP) and carbon-in-leach (CIL) recovery provided a process that allowed the treatment of lower grade and problematic ores (e.g., high-clay ores), at lower capital and operating costs and higher metal recoveries.

Gold CIL & CIP Gold Leaching Process Explained CCD

Highly activated carbon is used in the dissolved gold recovery process, either by introducing it directly into the CIL (carbon-in-leach) tanks or into separate CIP (carbon-in-pulp) tanks after leaching. The activated carbon adsorbs the dissolved gold from the leach slurry thereby concentrating it …
