Product Description Product Description Gold CIP Leaching Process ExplainedCIP ( Carbon In Pulp) process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high-grade silver as well. Generally, the proportion of gold and silver should not exceed 1:5. The best conditions for Carbon In Pulp process in China: PH=10-12, sodium cyanide concentration is not less than 0.015%, the particle size of activated carbon is 1.0-3.35mm, the best choice of carbon is coconut shell activated carbon, and the slurry concentration is 40-45%.CIP (Carbon In Pulp), also known as carbon slurry method for extracting gold. It is an unfiltered cyanide slurry process that directly uses activated carbon to adsorb and recover gold from cyanide slurry.The main steps of the Carbon Pulp Process (CIP) include feeding, crushing and screening, grinding, leaching pretreatment, leaching, activated carbon adsorption, gold-loaded carbon desorption and electrolysis, gold melting, carbon recovery and utilization, and tailings water recovery.1. Feeding+crushing screening processThe vibrating feeder evenly transports the raw ore to the jaw crushers, and the fine jaw crusher crushes the rock below 20-25mm. The +20mm material is back to the fine jaw crusher for further crushing. The 0-20mm powder material is transported to the ball mill for grinding.2. GrindingGrind the 0-20mm material from the jaw crusher into fine powder to release gold from the stone. The discharge from the ball mill enters the spiral classifier or hydrocyclone for classification. The return sand (bottom flow) from the classifier or cyclone will return to the ball mill for further grinding. The overflow of a classifier or cyclone are small particles, with 80% less than 200 mesh (0.074mm).3. Leaching pretreatmentPump the 200 mesh slurry to the thickener. Before the slurry enters the thickener, there is a safety screen to prevent coarse particles. The slurry under the screen directly enters the thickener, and it needs to add flocculants to the thickener to accelerate sedimentation. The overflow water from the thickener enters the sedimentation tank, and the settled water is recyclable. The function of a thickener is to allow the slurry to reach a certain concentration before entering the following leaching tank.4. Leaching:The bottom flow of the thickener will enter the mixing tank with a height difference. Then the slurry pump pumps the mixed slurry into the double impeller leaching tank and adds sodium cyanide, without activated carbon.5. Activated carbon adsorption treatmentAfter the gold is leached and dissolved in the solution, the slurry flows into the double impeller stirring adsorption tank at the back, where activated carbon is in it. The activated carbon adsorbs the gold in the slurry to become the gold-carrying carbon, then extracts gold by a carbon extractor.6. Desorption and electrolysis of gold loaded carbonThe gold-loaded carbon is filtered through a linear vibrating screen to remove impurities. The gold-loaded carbon enters a normal temperature and pressure desorption electrolysis system, and after electrolysis, obtains gold mud. Then dry the gold mud in an oven. Finally, use a gold melting furnace to melt the gold bars.7. Gold-loaded carbon recycling:The desorbed gold-loaded carbon can be dried in a drying oven and reused.8. Tailings water recovery system:The tailings from the adsorption tank first enter the linear screen to screen out the carbon shavings. The tailings slurry is pumped to the cone concentration tank to reach the appropriate slurry concentration before filtration. Then, the tailings slurry is fed to the plate filter press by a high-pressure pump for filtration and recovery of tailings water. The filtered dry tailings are transported by truck and the tailings flow into the water tank.If there is no request to recycle tailings water or treat tailings, add some bleaching powder to the tailings to treat acidic chemicals and reduce their impact on the environment. Then, the tailings can be discharged to distant places through water pipes.
