The Golden Triangle of Gold Recovery

As a premier global one-stop supplier of gold mining chemicals, United Chemical delivers an elite product line covering the complete metallurgical circuit: Leaching – Adsorption – Eco-Friendly Substitution. We empower global mining enterprises to break through extraction efficiency ceilings and maximize gold yield per ton.

AuCyan™ Premium Sodium Cyanide ≥98.3; The Industry Standard for Maximum Recovery

AuCyan™ represents United Chemical's pursuit of perfection in foundational mineral processing chemicals. As the most efficient traditional leaching reagent, we adhere to strict industrial standards to ensure batch-to-batch purity and stability, providing essential momentum for gold mining facilities worldwide.

• ≥98.3% High-Purity Standard: Purity levels far exceeding industry standards guarantee maximum active free cianuro ions (CN⁻) during cyanidation. This drastically accelerates gold/silver dissolution kinetics and maximizes overall leaching efficiency.

• Cost-Effective Consumption Control: Ultra-low impurity levels minimize unwanted side-reactions with accompanying minerals (such as copper, iron, and sulfur) in the leaching slurry, significantly lowering reagent consumption per ton of ore processed.

• Global-Grade Export Compliance & Delivery: As a regulated dangerous good, supply chain expertise is paramount. United Chemical holds robust UN-certified packaging solutions (steel drums, wooden boxes, Isotanks) and international export qualifications, guaranteeing smooth, safe, and compliant delivery to over 90 gold-producing nations.

AuCarb™ Gold Recovery Coconut Shell Activated Carbon – Precision Adsorption, Zero Gold Loss

In CIP/CIL processes, carbón activado quality directly determines final gold output. AuCarb™ is custom-developed for harsh agitation environments, refined from top-tier Sri Lankan and Southeast Asian Cascara de cocos through high-temperature activation and polishing treatments.

• Ultra-High Hardness & Attrition Resistance (Minimal Gold Loss): Mine operators fear carbon attrition in leach tanks leading to gold fines loss. AuCarb™ undergoes special hardening treatment to achieve a hardness rating above ≥99%, completely eliminating costly "gold-bearing carbon" breakdown.

• Rapid & High-Capacity Pore Architecture (High Adsorption Kinetics): Gold-cyanide complexes are larger molecular structures. AuCarb™ features a precisely controlled ratio of micro-pores to meso-pores, ensuring rapid entry and firm entrapment of [Au(CN)₂]⁻ complexes with loading capacity far surpassing standard activated carbons.

• Extended Service Life & High Reactivation Yield: Following desorption-electrowinning, AuCarb™ recovers over 95% of its original activity after thermal reactivation. It can be recycled through multiple cycles, significantly lowering carbon replacement costs per ton of gold produced.

AuLeach™ Gold Leaching Agent (GDA) – The Eco-Friendly Cyanide Substitute

Faced with increasingly stringent global environmental regulations (HSE), many gold mines face restrictions or bans on cyanide usage. AuLeach™ Eco-Friendly Gold Leaching Agent offers the perfect 100% green replacement for Cianuro de sodio, aligning "green mining" with high financial returns.

• 100% Seamless Direct Drop-in Replacement: Transitioning to AuLeach™ requires zero modification to existing cyanidation equipment (such as Heap Leaching or CIL circuits). It can be directly substituted for cianuro de sodio at 1:1 or recommended ratios to immediately start production.

• Non-Toxic Certification & Streamlined Approval (HSE Compliance): Officially certified as a general chemical (Non-Hazmat). This dramatically reduces ocean freight, land logistics, and insurance costs while eliminating tedious toxic chemical permit approvals, cutting mine commissioning lead times by over 50%.

• Faster Kinetics & Superior Performance on Refractory Ores: When treating complex, refractory gold ores containing arsenic or sulfur, AuLeach™ exhibits superior resistance to interference and faster leaching kinetics compared to NaCN, frequently achieving a 2% to 5% increase in absolute recovery rate.

• Safe Working Environment & ESG Value: Drastically reduces occupational health risks for operational personnel and minimizes environmental contamination hazards, making it the preferred reagent for modern mining companies seeking high ESG ratings.
