The changes made to the operating standards, the response of the circuit to these changes and the final Circuit layout and operating conditioning resulting in a 90% gold recovery are discussed. It was concluded that the distribution of oxygen and cyanide along the leach stream determined the extent of gold dissolution.

Although the earliest process was in South Africa in 1890, CIP/CIL was first introduced in gold processing in 1949 at San Andreas (Honduras) (Marsden and House, 2006). ... As the slurry passes through the circuit, gold continuously leaches in the cyanide solution. Sufficient residence time is provided in each tank to facilitate the leaching.

A typical CIP or CIL circuit is shown in Figure 1. The process is regulated by the elution schedule. Carbon addition and carbon transfer are based on when the required mass of carbon needs to be ...

Gold Processing Solutions for CIL/CIP Circuits continues to develop new, innovative, high capacity screening equipment to advance gold processing. Our efforts focus on reducing operational expenditure (OPEX), development of new patented technologies, and minimizing maintenance and footprint to reduce environmental impact.

As the slurry passes through the circuit, gold continuously leaches in the cyanide solution. Sufficient residence time is provided in each tank to facilitate the leaching. ... Using the same adsorption model, Kiranoudis et al. (1998) …

This document discusses the three main carbon adsorption processes used in gold mining: carbon-in-pulp (CIP), carbon-in-leach (CIL), and carbon-in-columns (CIC). CIP and CIL processes recover gold directly from pulp or slurries containing up to 55% solids, while CIC treats solutions, usually from heap leaching. The capital cost of a CIL plant is generally lower than CIP but it is …

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.

The model was used in a series of simulations to explore the influence on plant performance of: (1) circuit design encompassing tank size and number, and tankage configuration; (2) using some of the initial tanks for leaching only (CIP); (3) the impact of a thickener recycling a percentage of tailings solution to the head of the circuit; (4 ...

The higher the carbon inventory, the higher the gold recovery. However for high carbon inventory the gold lock-up in the CIP circuit is higher and a larger amount of a less loaded carbon has to be processed at the elution stage. The optimal fraction to be transferred depends upon the inventory.

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 affect the adsorption of gold are discussed. Finally, performance monitoring methods that help control the operation of the CIP/CIL process are discussed. 2.
