High Purity · Stable Performance · Higher Recovery — sodium cyanide for modern gold leaching

UC-98%+ Sodium Cyanide (NaCN) — United Chemical

United Chemical supplies premium, factory-produced Sodium Cyanide (NaCN) designed for high-efficiency gold leaching and industrial applications. Backed by more than 30 years of production and R&D experience, advanced continuous crystallization technology, and strict quality control, the UC‑98 series delivers stable purity, fast dissolution and consistent crystals — all essential for precise dosing, predictable performance and cost-effective processing.

Key Technical Reference (R&D insight)

Our R&D and field trials indicate that when NaCN purity is maintained at 98.0% or higher (NaCN ≥ 98.0%) and dosing is controlled around 0.25%–0.30% (with an observed optimal reference at ~0.28%), gold leaching recovery rates can exceed 93.7% under favorable conditions. This is provided as a technical reference only — actual optimal concentration and recovery depend strongly on ore type, plant circuit and operational variables. For mine‑specific recommendations please contact our technical team.

Core Advantages

• Ultra-high purity: Typical assay range 98.3%–98.8% NaCN; impurities ≤ 0.5% ensures predictable cyanidation chemistry.

• Fast dissolution: Up to ~33% faster dissolution compared with conventional products — accelerates leaching kinetics and shortens residence time requirements.

• Uniform crystal quality: Continuous crystallization produces consistent particle size and morphology for accurate metering and automated dosing systems.

• Improved economic performance: Field and pilot tests demonstrate significantly improved gold recoveries and lower reagent consumption per tonne of ore when product and dosing are optimized for the ore.

• Safety & compliance: Supplied in accordance with UN 1689; HS code 2837111000; full export documentation and quality certificates are available.

Typical Field Performance (Example)

• Trial (example): Gold leaching recovery 86.5% with reagent consumption around 0.8 kg/tonne. Reported reagent cost savings in the example project exceeded USD 2 million. Individual results will vary by ore and process.
