gold leaching and carbon in pulp circuits

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 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 at about 0.8 mm to remove any undersize carbon.

Carbon-In-Leach Jacobi Carbons

The activated carbon used in the carbon-in-leach circuit preferentially adsorbs the gold over the native carbon and allows the gold to eventually be recovered for stripping. Jacobi offers a full range of carbon products to serve the gold recovery industry.

Carbon-in-pulp ScienceDirect

Jan 01, 2005 Residual gold in solution is measured, and gold adsorbed on to the carbon is calculated as G 1. The carbon is recovered and put into a new fresh batch of 10 mg/L gold solution for a further hour. Gold adsorbed on to the carbon is calculated as G 2. This is repeated 11 times (or more if the carbon has high gold-loading capacity).

Jan 01, 2016 The pump-cell circuits were operated by moving all the carbon in a contactor every 2 days, with carbon concentrations of 25–50 g/L. Typical upgrade ratios (ratio of gold on loaded carbon to gold in feed at operating equilibrium) was found to be 800–1000 for the cascade CIP circuit and 1800–2000 for the pump-cell circuits. Soluble losses

Gold ore Carbon-In-Leaching (CIL) processing technology

The flotation tailings containing the unrecovered gold from the primary circuits are directed to the leaching plant and dissolved in an aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL).

Leaching and adsorption circuits for better metal extraction

The CIL circuit utilises combined leaching and adsorption tanks, meaning that this circuit has the capacity to complete both processes at the same time. This also means that cyanide, ore pulp, oxygen and carbon are all introduced together. In CIL, adsorption of gold and silver onto activated carbon is also completed in agitated tanks with

Estimating process design gold extraction, leach residence

May 01, 2015 Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropriate for ores that deplete

Carbon-in-Pulp or Carbon-in-Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism, which is a chemical occurrence.

Non-Cyanide Leaching Agitation Tank of Gold Processing

T he pulp diffuses along the radial direction at the bottom of the t ank then flows upward along the circular wall of the tank, thus a closed cycle is form ed. If the machine is used as a leaching tank, the leaching agent solution and air are filled into the tank, and the leaching agent and air are evenly distributed in the tank to leach gold.
