In the field of gold cyanide beneficiation, CIP (Carbon-In-Pulse) and CIL (Carbon-Leach-In) are two mainstream processes. Although both ultimately aim to adsorb gold using activated carbon, their equipment configuration logic differs significantly: one is a "step-by-step" process, while the other is a "simultaneous" process.

The CIP process employs a "leaching first, adsorption later" model. Its equipment flow includes separate cyanide leaching tanks and activated carbon adsorption tanks. The ore slurry must first dissolve the gold in a multi-stage series of leaching tanks before being transferred to a dedicated adsorption tank for recovery via activated carbon. This step-by-step operation requires two complete leaching and adsorption systems, resulting in a longer process and placing certain requirements on solid-liquid separation equipment.

The CIL process, on the other hand, implements a simultaneous "leaching and adsorption" process. Its core equipment is a carbon leaching tank that combines leaching and adsorption functions. By directly adding activated carbon to the leaching tank, cyanide leaching and activated carbon adsorption occur simultaneously within the same tank. This eliminates the need for a separate adsorption tank group in CIP, simplifying the material handling process.

Therefore, CIL (Clean Leaching) process equipment is more compact and has lower investment costs, making it particularly suitable for processing ores with high mud content and difficult filtration; while CIP (Clean Injection) process, although requiring more equipment, has independent processes, making it easier to optimize leaching and adsorption conditions separately, and is suitable for scenarios with high process control requirements. The choice of equipment for the two processes needs to be based on a comprehensive trade-off between ore properties and economic indicators.
