Inquiry about Laboratory-Scale Electrochemical System for Gold Recovery NEW

I need a laboratory-scale electrochemical system for recovering metals from acidic solutions, specifically gold derived from mining tailings. The system will be integrated with a locally supplied electrocoagulation unit as part of a hybrid process. Process details: - Medium: Sulfuric acid solutions (pH 0.5 - 2.5) - Matrix: Tailings leachates - Gold concentration: ~2.2 mg/L - Gold present as dissolved ionic species and micro/nano-sized particles. Application objective: - Controlled electrodeposition of gold at low concentrations, emphasizing high recovery efficiency and capability to handle colloidal/nano gold through enhanced surface capture. Technical requirements: - Power supply/electrochemical system: Galvanostatic control (mandatory), stable low-current operation, low ripple, suitability for long-duration experiments (up to 6-8 hours). - Electrodes: - Cathodes: High-surface-area materials like carbon felt, graphite, or equivalent. - Anodes: MMO-coated titanium or equivalent. - Monitoring and control: Real-time measurement of current and voltage; optional data logging and ORP integration. Additional requirements: - Compatibility with acidic environments. - Recommendations for optimal configuration for low-concentration gold recovery. - Technical data sheets. - Quotation options (EXW/FOB/CIF). - Delivery time.
