Hydrometallurgy Processing Aids

Application Scenarios

Suitable for hydrometallurgical operations including leach pulp thickening, counter-current decantation (CCD), solvent extraction pre-treatment and electrowinning feed clarification.

Applicable to copper, gold, uranium, nickel and other metal recovery circuits, with adaptability to acidic, alkaline and cyanide leaching systems and varying pulp conditions.

Solutions

Specialized polyacrylamide polymers optimize solid-liquid separation in hydrometallurgy, improving solution clarity, metal recovery and downstream processing efficiency. High-molecular-weight anionic grades handle leach pulp thickening and CCD, while low-residual grades protect solvent extraction and electrowinning operations from contamination.

• Efficient thickening and clarification of leach pulp streams.

• Improved solution recovery in counter-current decantation circuits.

• Low residual polymer to protect solvent extraction and electrowinning.

• Compatibility with acidic, alkaline and cyanide leach systems.

• Enhanced filtration rate for metal precipitate dewatering.

• Support for high-value metal recovery and process efficiency.
