Gold CIL CIP Line CIP CIL Gold Extraction 30TPD-2500TPD Capacity

1.Product Introduction

The Gold CIL/CIP production line employs the carbon-in-leach process, which directly adsorbs and recovers gold from cyanide pulp using activated carbon. This represents a widely applied key technology in modern gold extraction industries.

2.Application

• Flotation gold concentrate, or tailings from amalgamation or gravity separation.
• Silt-rich oxidized ore, characterized by high clay content and poor settling and filtration properties.
  Compared to traditional zinc powder replacement methods, the carbon-in-slurry process eliminates investment in solid-liquid separation equipment, reduces cyanide usage, and offers greater environmental benefits.This mature technology achieves high recovery rates, with gold ingots as the final product.

3.Working Principle

The Cyanide-in-Pulp (CIP) and Cyanide-in-Leach (CIL) production lines are gold extraction processes based on the adsorption principle of activated carbon. The core process involves preparing a pulp from crushed and ground gold ore, leaching it in a cyanide solution to dissolve the gold into a gold-cyanide complex. Subsequently, activated carbon adsorbs this complex to achieve gold enrichment and separation.

4.Advantages

• Process Simplification and Efficiency Enhancement: The CIL process integrates leaching and adsorption into a single operation, significantly shortening the production cycle, reducing the number of required equipment and plant footprint, and lowering capital investment. Its simultaneous operation eliminates the multiple separation steps between leachate and adsorbent found in CIP processes, resulting in a more streamlined workflow.

•  

  High Recovery Rates and Economic Viability: This process demonstrates excellent adaptability to low-grade oxidized gold ores, achieving gold recovery rates exceeding 98%. Through parameter optimization, it can also process ores with higher carbon content or more complex compositions. The streamlined process directly reduces operational costs.

•  

  Operational Simplicity and Adaptability: The production line features high automation, making it suitable for large-scale continuous production. The CIL process is applicable to various gold ore types, including ores with significant associated silver and copper content.

•  

  Environmental Performance Enhancement: The process employs a closed-loop circulation system, minimizing environmental discharge of reagents like cyanide and meeting modern environmental standards. Additionally, eliminating the need for filtration and washing of leached pulp avoids the wastewater treatment challenges associated with solid-liquid separation in traditional processes.
