2022年2月3日 This article serves to discuss the fundamental aspects of gold recovery utilizing the 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

2005年1月1日 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 800–1,000 for the cascade CIP circuit and 1,800–2,000 for the pump-cell circuits. Soluble ...
