High Silver "Cyanicide" Ratios (Santa Cruz)

Epithermal deposits in the Deseado Massif often contain massive amounts of silver alongside gold. Silver requires double the stoichiometric amount of cyanure to dissolve compared to gold, aggressively stripping weak reagent pools and crippling overall recovery if purity is compromised.

Freezing High-Altitude Kinetics (San Juan)

At altitudes exceeding 4,000m, freezing temperatures and severe oxygen depletion drastically slow the Elsner dissolution equation in Heap leach pads. In these conditions, only highly concentrated, aggressive free cyanide ions can maintain profitable extraction speeds.

Provincial Cyanide Bans (Mendoza/Chubut)

Due to Argentina's federal system, several provinces have enacted strict laws banning the use of toxic chemicals (like cyanide) in mining. Billions of dollars in gold reserves remain locked underground, desperately awaiting a non-hazardous, legally compliant leaching alternative.

1. How does AuCyan™ handle the high silver-to-gold ratios common in Santa Cruz?

AuCyan™ handles high silver-to-gold ratios by providing an ultra-high purity concentration (≥98.3%) of active Le cyanure de sodium. Epithermal deposits in the Deseado Massif (Santa Cruz) often contain significant silver, which requires nearly double the stoichiometric amount of cyanide to dissolve compared to gold. If reagent purity is low, silver consumes the active ions, leaving gold un-leached. Our guaranteed ≥98.3% purity ensures an overwhelming surplus of free CN⁻ ions to dissolve both silver and gold simultaneously, maximizing total precious metal recovery.

2. Which Argentine maritime ports do you utilize for CIF deliveries?

We utilize the Port of Buenos Aires and the Port of Puerto Deseado for secure CIF maritime deliveries to Argentina. To support Argentina's vast geographical spread, the Port of Buenos Aires is ideal for central and northern inland transport (such as San Juan and Salta), while the Port of Puerto Deseado is strategically located for operations in Santa Cruz and Patagonia. Once cleared through customs, your appointed local logistics firm handles the inland trucking to the mine site.

3. Can AuLeach™ GDA be used in Argentine provinces that ban cyanide?

Yes, AuLeach™ GDA can be used in Argentine provinces with cyanide bans because it is officially classified as a Non-Hazardous chemical globally. For mining concessions located in provinces (like Mendoza and Chubut) with strict legislative bans on toxic chemicals like le cyanure de sodium, AuLeach™ provides a fully compliant, eco-friendly pathway to unlock stranded gold reserves without violating provincial environmental mandates.

4. How does AuCyan™ perform at extreme, freezing altitudes in San Juan?

AuCyan™ performs exceptionally well at freezing altitudes by leveraging its ≥98.3% purity to create an intensely aggressive chemical environment that compensates for poor thermodynamics. At elevations above 4,000 meters in the Andes, freezing temperatures and low atmospheric pressure drastically reduce dissolved oxygen in process water, paralyzing normal leaching kinetics. AuCyan's high concentration sustains fast dissolution rates even in cold Heap Leach pads.

5. Why is a ≥99% hardness rating critical for AuCarb™ Charbon actif?

A ≥99% hardness rating is critical because it prevents the activated carbon from being crushed into dust during the violent mechanical agitation of CIP and CIL plants. If your activated carbon is soft, the impeller blades will grind it down, and this dust—saturated with your extracted gold and silver—will pass through the screens and be lost to the tailings. AuCarb™'s extreme structural integrity ensures zero attrition loss.

6. Do you provide cross-border railway transport to inland Argentine mines?

No, we strictly prohibit the use of international railway transport for our chemical exports. Due to severe international safety regulations governing the movement of hazardous chemicals and the unpredictability of high-altitude rail infrastructure, we secure our supply chain exclusively via maritime ocean container shipping (FOB/CIF) to destination ports.

7. Are there any capital expenditure (CAPEX) costs to switch to AuLeach™?

There are zero CAPEX costs required because AuLeach™ is engineered as a 100% drop-in replacement. Argentine plant managers do not need to purchase new leaching tanks, alter their Heap leach drip irrigation systems, or modify their carbon elution circuits. You simply substitute the cyanide with AuLeach™ while utilizing standard hydrated lime to manage the pH.

8. What is the Minimum Order Quantity (MOQ) for exporting to Argentina?

Our strict Minimum Order Quantity (MOQ) is 1x20' FCL (Full Container Load). This policy applies universally to AuCyan™, AuCarb™, and AuLeach™ to guarantee factory-direct pricing, protect the chemical packaging from damage, and optimize maritime freight costs across the Atlantic Ocean.
