CIP and CIL are two commonly used extraction processes in gold mining, relying on specific mining equipment to achieve efficient gold extraction.
Ⅰ. Overview of CIP & CIL Processes
CIP Process: The CIP process is suitable for processing low-sulfur oxidized gold ores and slurries. The process involves leaching gold ore with cyanide into an aerated alkaline slurry, and then recovering or concentrating the metal through activated carbon adsorption.
CIL Process: The CIL process is similar to the CIP process, also involving cyanide leaching and activated carbon adsorption processes, but the two may differ in specific operations and equipment. The CIL process generally adds activated carbon during the leaching process, while the CIP process performs adsorption after leaching.
Ⅱ. CIP & CIL Gold Mining Equipment

• Function: Break large rocks into smaller particles for further processing.
• Equipment: including feed hopper, chute feeder, jaw crusher, belt conveyor, fine jaw crusher, vibrating screen, roller crusher, etc.
2. Grinding system:
• Function: further grind the crushed stone into fine powder for better leaching of cyanide.
• Equipment: including storage bin, electromagnetic vibrating feeder, belt conveyor, ball mill, cyclone, etc.
3. Leaching pretreatment system:
• Function: pretreat the ground ore and adjust the parameters such as mud density and pH value.
• Equipment: including concentrator, stirring tank, etc.
4. Activated carbon leaching adsorption treatment system:
• Function: add cyanide solution during the leaching process to dissolve gold and form cyanide gold complex, and then recover gold through activated carbon adsorption.
• Equipment: including leaching stirring tank, adsorption stirring tank, Roots blower, garbage dewatering lining vibrating screen, carbon screen lining vibrating screen, carbon extractor, carbon screen, etc.
5. Gold-loaded carbon desorption electrolysis system:

8. Reagent addition system:
• Function: Add necessary reagents such as sodium cyanide, lime, etc.
• Equipment: Including reagent mixing tank, reagent slurry pump, reagent tank, etc.
Ⅲ. Equipment selection and configuration suggestions
Select equipment according to ore properties: Different ore properties require different equipment configurations. For example, for ores with high sulfur content and mud content, more complex pretreatment equipment may be required.
Consider production efficiency and cost: When selecting equipment, you need to consider production efficiency, equipment cost, operating cost and maintenance cost.
Choose a reliable supplier: Choose an experienced and reputable supplier to ensure equipment quality and after-sales service.
CIP and CIL gold mining equipment Ore dressing equipment involves multiple systems and multiple equipment, which need to be selected and configured according to the specific ore properties and production needs. When selecting equipment, you need to consider multiple factors to ensure maximum production efficiency and savings.
