Supporting the transition toward more responsible gold extraction methods without compromising production performance.
Modern mining operations are increasingly expected to balance recovery objectives with worker protection, environmental responsibility, regulatory readiness, and long-term operational resilience. A non-cyanide approach provides mining companies with an alternative pathway to evaluate safer and more accountable gold processing practices.
Gold extraction is fundamentally a controlled transfer process. Valuable gold must first be released from the ore, dissolved into a process solution, captured by an adsorption medium, and recovered through downstream refining.
A non-cyanide system follows the same metallurgical objective while using an alternative leaching chemistry and a more controlled circulation model.
During leaching, the reagent interacts with exposed gold surfaces and supports the formation of a soluble gold-bearing complex. Under controlled alkaline conditions, oxygen availability, agitation, and contact time influence the transfer of gold from the solid ore into the process solution.
Depending on the validated reagent formulation, this interaction may involve selective leaching behavior, ligand-based complex formation, or chelating interaction with gold-bearing species. The resulting dissolved gold can then be captured using activated carbon or another suitable recovery medium.
Final reagent behavior must always be confirmed through ore-specific bottle-roll testing, laboratory analysis, and controlled field trials.
Select a process mode, start the simulation, and follow how the material moves from ore preparation to gold recovery.
Crushing and milling expose gold-bearing mineral surfaces.
Water, pH control, reagent dosing, and oxygen are prepared under controlled conditions.
Gold transfers from the solid phase into a soluble gold-bearing complex.
Dissolved gold species are captured on activated carbon.
Gold-bearing carbon is processed for final metal recovery.
Process solution is monitored, adjusted, and recirculated to minimize uncontrolled discharge.
In a closed-loop configuration, process water and reagent-bearing solution are retained within controlled tanks, pipelines, adsorption units, and circulation systems. The solution is monitored and reused wherever operationally appropriate.
This approach does not eliminate the need for residue management, water testing, containment, or environmental controls. It reduces unnecessary discharge pathways and supports stronger process accountability.
Controlled circulation between process stages
Lower exposure to uncontrolled solution loss
Improved monitoring of reagent concentration
Better integration with water-management procedures
Process performance is influenced by ore mineralogy, particle size, reagent concentration, pH, oxygen transfer, contact time, temperature, carbon activity, and solution management.
Stable pH supports controlled reagent behavior and process consistency.
Aeration can influence oxidation and the kinetics of gold dissolution.
Sufficient residence time is required for leaching and adsorption.
Carbon quality and loading behavior affect dissolved-gold capture.
Gold must be sufficiently exposed before the reagent can interact effectively.
Each ore responds differently and requires individual testing.
