Leaching Chemicals
Chemicals for Gold Leaching and Recovery
MetSoP supplies chemical products used throughout the gold extraction process, from cyanidation and adsorption to elution and cyanide detoxification.
Our product range supports CIP and CIL circuits, helping operations manage the chemical requirements of gold leaching and recovery.
Our Leaching Chemical Range
Sodium Cyanide
A leaching agent used to dissolve gold from ore and transfer it into solution during cyanidation.
Activated Carbon
Used to adsorb dissolved gold from solution in carbon in pulp and carbon in leach circuits before elution.
Caustic Soda
Used during elution to support the removal of gold from loaded activated carbon.
Lead Nitrate
Used in certain cyanidation applications to improve leaching conditions and support gold dissolution.
Sodium Bisulfite
Used during cyanide detoxification to reduce residual cyanide concentrations before tailings discharge.
Sodium Metabisulfite
A chemical reagent used in cyanide detoxification and the treatment of residual cyanide in process streams.
Supporting the Gold Extraction Process
The performance of a gold leaching circuit depends on several connected factors, including ore characteristics, reagent dosage, residence time and process conditions.
Our metallurgical and analytical capabilities can support:
- Cyanidation test work
- CIP and CIL investigations
- Leach performance evaluation
- Activated carbon assessment
- Elution studies
- Cyanide detoxification test work
Responsible Chemical Supply
Leaching chemicals require appropriate handling, storage and transportation.
MetSoP supplies product information and relevant safety documentation to help clients manage these chemicals responsibly within their operations.
Support Beyond Chemical Supply
Our metallurgists can help evaluate leaching performance and identify suitable chemical requirements for your ore and process.
