Derived from organic marine algae, ExtracTech is a biopolymer with dual alkaline and oxidative action, designed to improve performance in the gold leaching stage.
Challenges ExtracTech Solves
▪ High dosage requirements of conventional alkalizing agents
▪ Unstable pH during processing, impacting recovery rates
▪ High cyanide consumption in leaching tanks
▪ Inefficient gold extraction caused by metallic contaminants
Operational Advantages of ExtracTech
▪ As a liquid, it is applied directly into the pulp, with no need for complex pre-treatment steps
▪ Facilitates gold leaching by removing interfering metals and potentially reducing cyanide consumption
▪ Complete replacement of the alkalizing agent
Savings with ExtracTech*
▪ Maintains the performance of traditional alkalizers, using up to x20 lower dosage
▪ Up to 3% increase in metallurgical recovery
▪ Up to 35% reduction in cyanide consumption
*Results may vary based on ore characteristics and operational conditions.
How ExtracTech Works
ExtracTech acts in two ways when in contact with ore:
▪ Alkalinizing Action – Adjusts and stabilizes pulp pH within the optimal range, ensuring consistent process control and predictability.
▪ Oxidizing Action – Triggers redox reactions with undesirable metals in the ore matrix, aiding their removal and improving gold liberation.
Additional benefits of ExtracTech
▪ Stable pH control throughout processing, minimizing fluctuations commonly seen with traditional alkalizing agents.
▪ Improved leaching kinetics, boosting overall process productivity.
