Advanced Gold Extraction Chemicals for South American Metallurgy
Conquering Complex Ores from the High Andes to the Amazon Basin
United Chemical supplies guaranteed purity AuCyan™ Sodium Cyanide NaCN (≥98.3%), AuCarb™ Gold Recovery Coconut Shell Activated Carbon (≥99% Hardness), and non-hazardous AuLeach™ Gold Leaching Agent (GDA) to empower Heap leaching, Vat leaching, CIP, CIL, and CIC operations across Peru, Brazil, Colombia, Chile, and the Guiana Shield.
The South American Mining Landscape: A Continent of Metallurgical Extremes
South America is an undisputed powerhouse in global gold production, yet it presents some of the most complex geological and metallurgical challenges on the planet. From the towering, high-altitude epithermal and porphyry deposits of the Andean Belt (Peru, Chile, Colombia, Ecuador, Bolivia, Argentina) to the dense, clay-rich laterite and saprolite soils of the Amazon Basin and Guiana Shield (Brazil, Suriname, Guyana, French Guiana, Venezuela), mineral processing facilities must be equipped with world-class, uncompromising chemical reagents.
United Chemical stands at the forefront of this industrial demand. With a verified export footprint spanning 77 + lannen, we manufacture and deliver chemical solutions engineered to penetrate refractory ores, withstand severe mechanical attrition, and comply with the increasingly strict Environmental, Social, and Governance (ESG) frameworks of South American governments.
To ensure secure and reliable supply chains, we strictly operate via maritime ocean freight. We support all continental operations under FOB (Sineeske havens) of Cif terms directly to major hubs—such as Port of Callao (Peru), Port of Santos (Brazil), Port of Buenaventura (Colombia), and Port of Guayaquil (Ecuador). Our operations require a Minimum Order Quantity (MOQ) of 1x20' FCL, guaranteeing factory-direct pricing and continuous supply for Koalstof-yn-pulp (CIP), koalstof-yn-útlûking (CIL), koalstof-yn-kolom (CIC), heapútlûking en vatútlûking circuits.
1. Unlocking Refractory Ores: Regional Processing Pain Points
Andean Cyanicide Interference
Gold deposits along the Andes (especially in Peru and Chile) are frequently associated with high levels of copper and silver minerals (cyanicides). These base metals consume massive amounts of weak or impure syanide, drastically slowing down gold dissolution kinetics and inflating chemical OPEX.
Amazonian Clay & Slurry Attrition
In the Guiana Shield and Brazilian laterite zones, ores exhibit extremely high clay content and high pulp viscosity. In intense CIP/CIL agitation tanks, low-grade activated Koalstof is easily crushed, leading to catastrophic "carbon fines" generation and irreversible precious metal loss.
Strict ESG & Environmental Bans
Governments in Colombia, Ecuador, and Brazil are aggressively tightening environmental regulations, heavily restricting the use of FERGESE and monitoring traditional cyanidation. Plant operators are urgently seeking non-hazardous leaching alternatives to navigate sensitive ecological biomes.

Faak Stelde Fragen
Q1: How does AuCyan™ handle high copper-gold porphyry ores in the Andes?
Copper is a notorious "cyanicide" that rapidly consumes weak cyanide. AuCyan™ Natriumcyanide NaCN is manufactured with an ultra-high purity of ≥98.3%. This robust concentration ensures that even after base metals consume a portion of the reagent, sufficient free cyanide ions (CN-) remain available to drive fast and complete gold dissolution.
Q2: Which South American ports do you ship to under CIF terms?
United Chemical offers comprehensive maritime logistics to all major South American commercial ports. We regularly quote CIF terms to Callao (Peru), Santos and Paranaguá (Brazil), Buenaventura and Cartagena (Colombia), Guayaquil (Ecuador), and Valparaíso/San Antonio (Chile). All inland transportation from the destination port is handled by the buyer's local logistics agent.
Q3: Why is a ≥99% hardness rating essential for Aktivearre koalstof in the Amazon?
Ores mined in the Guiana Shield and Amazon basin are often lateritic and highly viscous. The heavy mechanical agitation required in CIP/CIL tanks causes immense shear stress on carbon granules. AuCarb™ Gold Recovery Kokosnootskulp Aktivearre Koalstof guarantees a ball-pan hardness of ≥99%, ensuring the carbon does not crush into fine dust and carry your adsorbed gold out to the tailings facility.
Q4: Is AuLeach™ GDA truly classified as non-hazardous for import into Colombia or Brazil?
Ja. AuLeach™ Gouden Útloakingsagint is officially certified as a Non-gefaarlik chemical for maritime transport and import. This classification is vital for mining operations in environmentally sensitive regions (like the Amazon or Andean paramos), as it bypasses the severe restrictions, military escorts, and complex permitting associated with toxic cyanide imports.
Q5: Do you use railway transport to reach landlocked regions like Bolivia?
No. Due to international hazardous goods restrictions and unpredictable freezing conditions at high altitudes, we strictly do not use railway transport for our chemical exports. We ship exclusively via ocean freight (e.g., CIF Port of Arica or Iquique in Chile for Bolivian transit cargo), after which local licensed trucking companies take over.
Q6: Will we need to modify our CIP/CIL plant to use the AuLeach™ Non-Hazardous agent?
Not at all. AuLeach™ is formulated as a 100% drop-in replacement for traditional cyanidation. You can utilize your existing agitation tanks, carbon columns, and electrowinning cells without spending any capital on equipment retrofits.
Q7: What is the Minimum Order Quantity (MOQ) for South American shipments?
To maintain optimized factory-direct pricing and ensure maritime shipping efficiency across the Pacific or Atlantic, our strict MOQ is 1x20' FCL (Folsleine kontenerlading) across all product lines.
Q8: Can we test your products before placing a full 1x20' FCL order?
Yes, we highly recommend laboratory validation. We offer complimentary test samples of our AuCarb™ Aktivearre Koalstof en AuLeach™ Net-gefaarlike GDA. This allows your metallurgical team to conduct bottle roll and column tests to verify adsorption kinetics and recovery rates on your specific ore before committing to bulk commercial shipments.
