Carbon-slurry interaction can be maximised by feeding slurry into the tank at or near the surface, while drawing pulp onto the screen from an upcomer. Carbon recycled off the screen must traverse the entire tank height before returning to the inter-stage screen. As depicted in Figure 4, this flow pattern minimizes both carbon and slurry short ...

Carbon-In-Pulp. With carbon-in-pulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. The granular activated carbon is added to the leached slurry, where the carbon adsorbs the gold from the slurry solution and is then removed from the slurry by coarse screening.

The amount of carbon in each 392 m3 carbon in pulp tank is the main determining factor for gold extraction efficiency. Each tank requires up to 12 tonnes of carbon and 5 ppm dissolved oxygen to concentrate 93 – 96 % of soluble gold at 95 % carbon activity rate, achieving up to 10,000 ppm gold-cyanide in feed and 0.001 ppm in tails solution.
Abstract. Despite major advances in the practical use of the carbon-in-pulp (CIP) process, the dynamics of this process are still poorly understood by operating staff. Moreover, the many features of existing models for the CIP process are frequently not appreciated by production personnel. It is the aim of this paper to review and compare ...

A steady-state simulator for CIP/CIL circuits has been developed. The simulator is based on a model of a single CIL tank. This model combines descriptions of the kinetics of leaching, the kinetics of adsorption, and the residence time behaviour of the pulp solids, leach liquor and carbon. This work was part of a co-operative research …

Another is the all-slime cyanidation ( CIP process and CIL process ), which adopts activated carbon to absorb and recover gold from cyanide pulp directly without filtration and washing.
One of the main bottlenecks in the carbon-in-pulp process for the recovery of gold is the elution procedure, which typically requires the heating of caustic cyanide eluants to high temperatures ...

The pressure drop around the wedge wire screen is compensated by an up-pumping impeller ...
The cyanide pulp enters the stirring adsorption tank (carbon slurry tank). Add carbon to the leaching tank, and the carbon adsorbs the gold in the pulp to become gold-loaded carbon. After the adsorption is completed, the carbon and the pulp are separated by a carbon extraction screen.
In the absorption stage, this solution flows through several agitation tanks containing activated carbon. Gold absorbs on to the activated carbon, which flows counter-current to the pulp, while screens separate the barren pulp from the gold-loaded carbon.
steel equipment is normally used. Manual control is the standard. Fluctuations in flow and temperatures can reduce stripping efficiency but the only adverse effect is an extension of the required stripping cycle time. After the desorption vessel has been filled with loaded carbon and solution flow is started, the only operator attention required is periodic …
