1. Conquering Guatemalan Operational Bottlenecks
Intense ESG & Community Opposition
Mining projects in Guatemala frequently face suspensions due to community protests and strict MARN environmental audits regarding toxic cyanide usage. An eco-compliant, non-hazardous leaching alternative is no longer optional; it is essential for project survival.
High-Silver Volcanic Cyanicides
Guatemalan epithermal deposits are exceptionally rich in silver. Because silver requires double the stoichiometric amount of cyanide to dissolve compared to gold, low-purity reagents are instantly exhausted, causing gold recovery yields to crash.
Rugged Inland Logistics Risks
Transporting highly toxic DG Class 6.1 chemicals from coastal ports into the mountainous interior involves navigating rugged, rain-slicked terrain. A transport accident involving cyanide would trigger a devastating and irreversible ecological and PR disaster.

Our guaranteed high purity ensures an overwhelming surplus of free CN⁻ ions to dissolve both metals simultaneously, preventing base metals from exhausting your reagent supply.
4. Why is a ≥99% hardness rating essential for activated carbon in high-silver CIL circuits?
A ≥99% hardness rating prevents activated carbon from shattering under the immense weight of adsorbed gold and silver complexes. In CIL operations, mechanical agitation combined with heavy silver loads will grind soft carbon into fine dust. AuCarb™'s extreme structural integrity ensures zero attrition loss, preventing your precious metals from washing into the tailings.
5. Can AuLeach™ reduce inland transport risks in mountainous Guatemalan regions?
Absolutely. Transporting toxic cyanide (DG Class 6.1) on winding, rain-slicked mountain roads from coastal ports poses a severe ecological risk if an accident occurs. AuLeach™ is classified as general cargo, completely eliminating the devastating environmental and PR disaster potential of a toxic spill during inland transit.
6. 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. Plant managers do not need to purchase new leaching tanks, alter their Heap leach irrigation systems, or modify their carbon elution circuits. You simply substitute the cyanide with AuLeach™ directly into the process.
7. What types of ores can be processed using the AuLeach™ Non-Hazardous reagent?
AuLeach™ has a very broad application spectrum. According to its Technical Data Sheet, it is highly effective on primary ores, oxide ores, semi-oxide ores, sulfide ores, gold concentrates, and cyanide tailings across both Carbon-in-Pulp and Heap leaching operations.
8. How do metallurgical labs in Guatemala test the concentration of AuLeach™?
Laboratories test AuLeach™ concentration via a standard chemical titration method. This involves using an analytical grade silver nitrate complexing agent and a rhodanine indicator. During titration, the solution changes from yellow to red, and the milliliters of complexing agent consumed precisely indicates the reagent's active concentration.
9. What is the optimal pH range for utilizing AuLeach™ in leaching circuits?
The guaranteed operational pH range for AuLeach™ is between 10.5 and 12. This aligns perfectly with traditional cyanidation circuits, meaning plant operators can continue using standard hydrated lime to manage slurry alkalinity without altering their current procedures.
