CFD Modelling of Flow and Solids Distribution in Carbon-in-Leach .Oct 28, 2015 . Carbon-in-Leach (CIL) circuit is a process that concentrates gold from 2.5 to 3.5 g/t in ore to 10,000 to 15,000 g/t . Efficient operation of CIL tanks requires suspension of the ore particles in the leaching solution and hence, to .. Axial concentration profiles at different stirrer speeds and off-bottom clearance.carbon in leach agitator,mineral processing - gold leaching - Integral Process Equipment(Carbon-In-Leach), tanks where cyanide, oxygen and activated carbon are added. The oxygen and cyanide dissolve the gold, which is then absorbed onto the activated carbon. The carbon loaded with the gold is screened out of the slurry and processed further to make gold bars. To design the agitators to maximize the.dynamic simulation of the carbon-in- pulp and carbon-in-leach .Abstract - Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, . the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously.

Leaching Plant Design - 911 Metallurgist

Mar 17, 2017 . Leaching plants, faced with increased tonnage, coarse (up to —3/16″ solids) feed, longer retention time, erosion, corrosion and the high cost of space, must be compact, simple and highly efficient. The engineer faced with the obvious economy of using a few large agitators compared to many smaller units.

Afromix: Agitators and pumps in various applications

CIL and CIP. Adsorption is most commonly recognized as Carbon in Leach (CIL) or Carbon in Pulp (CIP) the processes use activated carbon for the gold to leach onto. CIL is a process of cyanidation as the carbon is added into the leach or reactor tanks. Leaching as well as adsorption will take place in the same leach tanks.

Kemix - Carbon Adsorption

There are predominantly three methods employed in industry to adsorb leach gold from a pulp stream onto activated carbon. The methods are Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Pumpcell technology. CIL and CIP are typically counter current operations while the Pumpcell technology makes use of the.
