Gold Mine CIP Production Line and Process Flow Solution

Gold Ore CIP (Carbon In Pulp) Production Line Solution is the industry standard for high-efficiency gold extraction.

This process is ideal for processing flotation concentrates, gravity tailings, and oxidized muddy ores. By using activated carbon to adsorb gold directly from the cyanide pulp, it achieves recovery rates of >95% with simplified operations.

Step 1: Crushing & Grinding (Preparation)

Goal: Grind ore to -200 mesh (85-90%) to expose gold particles.

• Crushing: Jaw Crusher + Cone Crusher reduce rock size.
• Grinding: Ball Mill works with a Classifier to ensure optimal particle size for leaching.
• Trash Removal: Remove wood chips and debris to prevent screen blockage.

Step 2: Leaching & Adsorption

Goal: Dissolve gold into solution and adsorb it onto carbon.

• Leaching: Pulp flows through a series of Leaching Tanks where cyanide dissolves the gold.
• Adsorption: Activated carbon flows counter-current to the pulp, adsorbing the dissolved gold.
• Carbon Screens: Inter-stage screens prevent carbon from moving downstream while allowing pulp to pass.

Step 3: Desorption & Electrolysis

Goal: Strip gold from carbon and recover it as metal.

Step 4: Smelting & Carbon Regeneration

• Smelting: Gold mud from electrolysis is smelted into 99.6% purity gold ingots.
• Regeneration: Barren carbon is acid-washed and thermally regenerated for reuse.

Project: Oxidized Gold Ore CIP Plant

• Raw Ore: 3.5 g/t Gold (High mud content).
• Process: Crushing -> Grinding -> 8 Leaching Tanks -> High Pressure Desorption.
• Recovery Rate: 92%.
• Product: 99.6% Purity Gold Ingot.

Q1: What is the difference between CIP and CIL?

A: In CIP (Carbon-In-Pulp), leaching happens first, followed by adsorption in separate tanks. In CIL (Carbon-In-Leach), leaching and adsorption happen simultaneously in the same tanks. CIL generally has lower capital costs, while CIP is better for complex ores.

Q2: Why use High-Pressure Desorption?

A: It drastically reduces processing time from days to hours, lowers energy consumption by 50-75%, and eliminates the need for toxic cyanide during the stripping process, making it safer and cheaper.

Q3: How do you handle tailings?

A: Tailings are treated to destroy residual cyanide (using INCO or Chlorine methods) and then dewatered using a Filter Press for dry stacking or backfilling, ensuring environmental compliance.
