Kemix

A counter current method involves pulp flowing down a series of tanks with a reduced flow pumping carbon up the series of tanks to maximize gold on carbon loadings and minimize gold losses to tails. The interstage screens prevents carbon going down the circuit. MPS and MPS(P) Interstage Screens are semi-submerged top exit type screens.

Gold Carbon-in-pulp (CIP) Process

The gold CIP process includes seven operation stages: preparation of leaching pulp, cyanide leaching, carbon adsorption, gold-loaded carbon desorption, electrolysis to obtain muddy gold, de-gold carbon recycling, and treatment of leaching pulp.. Preparation of leaching pulp Grind the gold-containing material to a particle size suitable for cyanidation, generally less than 28 mesh.

Application Note Cyanide Leach Process

Carbon adsorption is often used to isolate the aurocyanide complex. This is typically referred to as CIP (Carbon In Pulp). Sometimes the leaching and carbon adsorption steps are combined. This is referred to as CIL (Carbon In Leach). The pulp from the leach circuit is cascaded through 4-6 tanks via gravity ﬂ ow. Activated carbon is

The process design of gold leaching and carbon-in-pulp …

The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation. The eluted and regenerated carbon is screened ...

CIL Gold Mill Flowsheet -Carbon In Leach

What is an interstage screen?

Pulp flows through the wedge wire screen apertures while carbon is retained. The pulp flows upwards through the inside of the screen and exits via a launder interface above the wedge wire screen and volute interface. ... interstage screens are installed in circuits where the tanks and operating pulp levels are at the same horizontal elevation ...

Carbon - in - Pulp (CIP) adsorption circuit [3]. Resulting from a successful pulp screening campaign conducted by AAC, the mechanically swept AAC NKM interstage screen was developed. Kemix (Pty) Ltd made a number of improvements to the AAC NKM interstage screen resulting in the development

Carbon Scout

By advancing the accuracy, regularity and consistency of sampling, the self-contained, ground-level unit will improve measurements in carbon-in-leach and carbon-in-pulp circuits to an accuracy of ±0.5 grams of carbon per litre of pulp.

Leaching and adsorption circuits – for better metal extraction

Our adsorption circuits include the Carbon in Column (CIC) circuit, the Leach - Carbon in Pulp (CIP) circuit, and the Carbon in Leach (CIL) circuit, all have similarities, but differ when it comes to the leaching and adsorption process.

Counter-current vs co-current flow in carbon-in-pulp adsorption circuits

Carbon-in-pulp (CIP) and carbon-in-leach (CIL) technology is applied successfully to recover gold from cyanided pulps. These plants are operated on a counter-current basis allowing for small concentrations of gold to be recovered at the expense of inefficiencies such as back-mixing, additional carbon breakage by interstage pumps and difficulties in carbon …

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 …

"The design of carbon-in-pulp (CIP), and carbon-in-leach (CIL) adsorption circuits has essentially remained unchanged since the early days of the carbon process for gold recovery. For CIP circuit the pulp residence time is traditionally fixed at one hour per contactor with a carbon concentration of between 15 and 20 grams per litre, and the counter current …

Dynamic Modelling of a Carbon-in-leach Gold …

Carbon-in-pulp (CIP) and carbon-in-leach (CIL) circuits have been the primary methods used for treating gold ores for many years. Although inherently robust processes, there is still often much room for optimisation to improve gold extraction efficiencies and to reduce reagent consumption and operating costs.
