nominal throughput of 500000, t/year through a hybrid carbon-in-leach (CIL) plant to recover gold as bullion. Sulphide ores will be treated at a nominal throughput of 250,000 t/year through a conventional froth flotation plant to produce a copper-gold concentrate. A block diagram showing the overall flow sheet is shown in Figure 1. This process ...

Basic Flow Sheet Part 2 • 5. Leaching & Adsorption A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes

Introduction to Cyanide Gold Mining

Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process.

Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

Cyanide Leaching Of Gold - Mine Engineer.Com

This process is very similar to the CIP process. The main differences lie in the preparation of the slurry and method for removing the gold from the leachate. In a CIL process, the carbon is mixed with the leachate solution, not with pulp. This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP process.

circuit. In a CIL plant, the carbon granules are added directly into the gold leaching tanks, so that leaching of gold (from the ore phase to the leachate), and adsorption of gold (from the leachate to the carbon), occur simultaneously. In a CIP plant, a series of small adsorption tanks is installed after the leach plant and the leaching ...

The Metallurgy of Cyanide Gold Leaching – An Introduction ...

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. Factors that

The CIL (Carbon in Leach) circuit is an intermediate stage in the production of gold. The process involves dissolving the solid gold particles into solution using a process know as cyanidation. The dissolved gold in solution is adsorbed onto activated carbon. When the carbon is loaded with enough gold it is removed from the circuit and sent to ...

Gold Mining Process Development – Denver Mineral Engineers

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.
