How to improve gold recovery by combining flotation with CIP/CIL cyanide?

/in /by

Gold ore processing often requires a combination of beneficiation methods to achieve the highest recovery rates. Among these, cyanidation remains the most widely applied technique, while flotation plays an important role both as a pre-treatment step and as a complementary process. By integrating flotation machines with the CIP/CIL cyanidation process, recovery efficiency is significantly improved. Our company specializes in this integration and provides comprehensive after-sales service, ensuring the long-term stability of gold recovery operations.

Role of Flotation in Gold Cyanidation

Flotation is a widely used beneficiation method for gold-bearing sulfide ores. By using flotation cells, sulfide minerals containing gold can be selectively separated from gangue, producing a concentrate that is richer in gold. This concentrate can then be subjected to cyanidation, where the gold is efficiently leached and recovered.

The advantages of applying flotation before cyanidation include:

  • Removal of sulfide minerals that consume cyanide, reducing reagent costs.
  • Enrichment of gold into a smaller volume of concentrate, improving leaching efficiency.
  • Flexibility in treating complex ores, including gold-copper, gold-lead, and polymetallic ores.

Types of Flotation Machines in Gold Processing

Different flotation machines are used depending on ore characteristics and processing goals:

  • Mechanical Agitation Flotation Cells (SF, BF, JJF types): Widely applied due to their strong aeration capacity and adaptability to various ores.
  • Pneumatic Flotation Cells (KYF, XCF types): Known for lower power consumption and effective handling of complex ores with fine particles.

These flotation machines are often used in combination with leaching agitation tanks, CIP/CIL adsorption systems, and desorption electrolysis equipment to form a complete gold extraction line.

Integration with CIP/CIL Cyanidation

The CIP (Carbon-in-Pulp) and CIL (Carbon-in-Leach) processes are highly effective for recovering gold from flotation concentrates. In these processes:

  1. Gold-bearing concentrate from flotation is mixed with activated carbon in a cyanide solution.
  2. The carbon adsorbs the dissolved gold, which is later desorbed and recovered in the form of pure gold.
  3. This method allows for high recovery rates while minimizing gold loss in tailings.

By combining flotation and CIP/CIL cyanidation, difficult ores can be processed more efficiently, ensuring maximum recovery.
