Description
Atomfair Cyanide-Free Gold Desorption & Extraction System (Atomfair-CFGD759)
1. Core Advantages (Compliant with International Standards)
– Safe Extraction: No cyanide or flammable organic substances are used in the entire process, eliminating potential safety hazards.
– Fast Efficiency: The complete desorption and extraction cycle only takes 8–12 hours, significantly shortening production time.
– High Purity Output: The directly precipitated gold sludge has a purity of 95%–99%, which can be sold directly without additional smelting and purification.
2. Key Equipment Composition
– Water Treatment System
– Electric Control Heating System
– Pre-leaching System
– Rinse System
– Reaction Gold Precipitation System
3. Core Technical Specifications
– Material: Entirely made of high-quality stainless steel for durability and corrosion resistance.
– Residual Carbon Gold Content: <100 g/T
– Gold Content in Post-Precipitation Waste Liquid: <0.5 g/T
– Desorption Method: Pure water desorption without any chemical reagents
– Post-Desorption Usage: Loaded gold carbon can be reused directly without regeneration
4. Working Process
1. Pre-leaching: Add a certain concentration of pre-leaching solution to the loaded gold carbon particles and heat to above 90°C, then discharge the pre-leaching solution.
2. Rinse: Use deionized water to rinse the pre-leached loaded gold carbon to elute the gold cyanide complex anions (Au(CN)₂⁻).
3. Gold Precipitation: Add the special chemical reagent (GSR) to the desorbed precious liquid for reaction and precipitation to obtain gold sludge, which can be further processed into gold ingots.
5. Application Scenarios
Specialized for the rapid desorption and extraction of loaded gold carbon obtained from heap leaching, tank leaching, and carbon-in-pulp (CIP) processes in gold mines. It replaces traditional processes requiring electrolysis, simplifying operations and reducing losses, making it an ideal choice for gold mining enterprises worldwide.
