Gold CIP Processing

Gold CIP Processing Introduction

Processing capacity: 10 TPH, 50 TPH, 100TPH, 200 TPH, and more. (customizable) From small pilot plants to large industrial projects.

Main Process: crushing and screening, grinding and classifying, leaching and adsorption, desorption and electrolysis systems, regeneration and tailings treatment, gold mud smelting.

The gold CIP (Carbon-in-Pulp) processing is an electrolysis gold extraction method that uses activated carbon to absorb gold-cyanide complexes from gold ore slurry. It is mainly suitable for beneficiating gold-containing oxidized ore with high slime content and containing carbon ore.

The gold CIP (Carbon-in-Pulp) process uses activated carbon for adsorption based on oxidation leaching, which can increase the gold leaching rate. It mainly involves using activated carbon to adsorb gold from a cyanide solution, then eluting and regenerating the carbon for reuse.

Flow includes crushing, grinding, leaching pretreatment, leaching, activated carbon adsorption processing, gold-loaded carbon desorption and electrolysis stage, and tailing water recycle system.

• Crushing, grinding: The ore is first crushed and ground to extremely fine particle size to match the size of the subsequent gold extraction process.
• Leaching: Usually, cyanide is added to the slurry as a leaching agent to help dissolve the gold in the ore.
• Adsorption: It involves the introduction of activated carbon into the slurry, capable of selectively adsorbing gold from the slurry.
• Carbon separation: A slurry containing gold-loaded carbon particles is passed through screens or filters to separate the carbon from the slurry.
• Gold elution & electrowinning: Using chemical cleaning agents to gold from carbon → recover 99.9% pure gold via electrolysis cells.
• Smelting: The gold deposited on the cathode is usually melted and refined by smelting to cast it into bullion or other forms.
• Regeneration: Spent carbon is heated to high temperatures, usually in a kiln or furnace, to remove impurities and restore its adsorption capacity.
• Tailings treatment: Tailings contain various chemical substances or minerals, usually stored in tailings ponds for further reprocessing.
