United Chemical AuCyan™ Series:
Premium High-Performance Sodium Cyanide
The "Kinetic Engine" of Gold Leaching: Where Purity Meets Profit
In the modern gold mining landscape, the gap between standard recovery and peak efficiency is defined by reagent precision.
United Chemical, with 26+ years of frontline expertise serving 77 countries, presents the AuCyan™ NaCN Series—not just a chemical, but a meticulously engineered leaching engine.
1. Technical Specification: The 98.3% Purity Standard
Surpassing industry benchmarks, our latest production batches consistently achieve "Superior Quality" grades. Below is the certified performance data (Ref: Batch C050030HS251101).
| Testing Items | Standard (GB/T 19306-2003) | AuCyan™ (Typical) | Operational Impact |
|---|---|---|---|
| Sodium Cyanide (NaCN) | ≥ 98.0% | 98.3% | Maximum gold dissolution kinetics and recovery rates. |
| Sodium Hydroxide (NaOH) | ≤ 0.5% | 0.13% | Superior pH stability; prevents premature hydrolysis. |
| Sodium Carbonate (Na2CO3) | ≤ 0.5% | 0.18% | Minimized impurity interference in the leaching solution. |
| Moisture (H2O) | ≤ 0.9% | 0.3% | Enhanced solid stability during long-term storage and sea transit. |
| Insoluble Substances | ≤ 0.05% | 0.02% | Anti-clogging formula; protects critical pumps and nozzles. |
2. Deep Technical Interpretation: Why the Details Matter
To a professional mine manager, these numbers are not just statistics—they are the key indicators of operational health and metallurgical certainty.
The 0.02% Insoluble Advantage
In Heap Leaching and CIL circuits, water-insoluble matter is the silent enemy. AuCyan™ reduces this to a negligible 0.02%, ensuring continuous operation with zero downtime for nozzle cleaning and extended equipment longevity by reducing abrasive wear on dosing pumps.
Precision Alkalinity Control
Maintaining a strict 0.13% NaOH level prevents the passivation of gold surfaces in specific ore types. AuCyan™ allows for precise pH modulation, ensuring the chemical environment is optimized solely for gold complexation rather than neutralizing excess alkaline impurities.
High Kinetic Recovery
The 98.3% purity standard ensures a higher activity of CN⁻ ions. This triggers accelerated leaching kinetics, which is critical for processing refractory ores or maximizing throughput in high-capacity metallurgical plants.
3. Strategic Synergy: The "1 + 1 + 1 > 3" Framework
United Chemical delivers the certainty of profit through vertical integration. AuCyan™ is engineered to work in molecular harmony with our ecosystem:
✔AuCarb™ Activated Carbon: High-purity leaching creates a "cleaner" pregnant solution, allowing our high-hardness coconut shell carbon to adsorb gold with maximum efficiency and minimal pore interference.
✔AuLeach™ Eco-Reagents: For mines with strict environmental mandates, our reagents provide a hybrid path to sustainability without sacrificing recovery benchmarks.
