Wedge Wire Interstage Screen Used for CIP and CIL in Silver Gold Recovery

Wedge wire interstage screens are pivotal in efficient and reliable silver and gold recovery. Used extensively in Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes, these screens enhance the recovery of precious metals while ensuring optimal carbon retention. 

The Role of CIP and CIL Processes in Precious Metal Recovery

The CIP and CIL processes are widely employed in extracting gold and silver from ore. Both methods involve activated carbon to adsorb dissolved gold and silver from a cyanide solution. The difference lies in the sequence of leaching and adsorption:

- CIP (Carbon-in-Pulp): Leaching occurs first, followed by the adsorption of gold and silver onto activated carbon.

- CIL (Carbon-in-Leach): Leaching and adsorption occur simultaneously, offering a more integrated approach.

In both processes, efficient separation and retention of activated carbon are critical, where wedge wire interstage screens prove indispensable.

What Are Wedge Wire Interstage Screens?

Wedge wire interstage screens are specialized stainless steel screens used in CIP and CIL tanks. These screens are usually made of stainless steel 304 material, featuring:

▪ Resist wear and corrosion: Withstanding the harsh chemical and physical conditions typical in mining environments.

▪ Retain activated carbon: Preventing the loss of carbon particles during the leaching process.

▪ Ensure high flow rates: Facilitating the seamless movement of slurry through the system.

▪ Non-cloogle: Wedge wire structure, not easy to clog.

The wedge wire screen design ensures durability and reliability, making them a preferred choice for gold and silver recovery operations.

Key benefits of Wedge Wire Interstage Screens

▪ High Efficiency in Carbon Retention

Wedge wire interstage screens are designed with precision slots that effectively trap activated carbon while allowing the free flow of slurry. This minimizes carbon loss and maximizes gold and silver recovery rates.

▪ Durability and Corrosion Resistance

Made from stainless steel, these screens resist corrosion and wear caused by abrasive materials and harsh chemicals in CIP and CIL processes.

▪ Customizable Designs

Interstage screens can be customized to fit various tank sizes and process requirements. This adaptability ensures optimal performance for specific mining operations.

▪ Reduced Maintenance Requirements

The robust construction of wedge wire screens minimizes the need for frequent maintenance, reducing downtime and operational costs.

▪ Enhanced Flow Rates

With their high open area design, these screens promote efficient slurry movement, improving the overall efficiency of the CIP and CIL processes.

Applications of Wedge Wire Interstage Screens in Mining

▪ Gold and Silver Recovery: Ensuring the effective separation of activated carbon from slurry during precious metal extraction.

▪ Carbon Retention: Preventing carbon loss to improve the efficiency of leaching and adsorption processes.

▪ Mining Operations: Supporting hydrometallurgy processes with reliable and durable screening solutions.

The wedge wire interstage screens provide an efficient and durable solution for carbon retention and slurry filtration, ensuring optimal performance in CIP and CIL processes.
