Gold cyanidation remain the most used gold processing technology.  IGS expert being associated with many gold processing scheme development and optimisation projects, can bring an added value to your project development and thus guide your testing program to be well suited to your deposit and earlier in the project cycle.  Our gold cyanidation testing capabilities cover the free gold milling to the most refractory gold bearing minerals:

• Direct Cyanide Leaching
• Carbon in Leach (CIL)
• Carbon in Pulp (CIP)
• Stirred Cyanide Leach – Vat & Bottle
• Carbon Activity & Carbon Characterization
• Carbon Loading for modelling
• Heap Leach Simulation (COBR & Column Testing)
• Oxygen Uptake Rate Determination
• Lime Demand
• Oxygen Enhanced Leaching
• Preg-Robbing Characterization
• Cyanide Detox and Destruction
• Arsenic Precipitation
