摘要: Abstract A clean and effective activated carbon modification method aimed at the cleaner production of gold using was investigated in this paper. Activated rich nitrogen sulfur (H-AC) synthesized by a simple method. The adsorption performance H-AC experiment, which capacity 25.8 kg/t achieved on H-AC. materials were characterized FT-IR, SEM, EDS XPS, results identified that carbon’s successful. Furthermore, Au(S2O3)23− may be ligand interchange mechanism. Last, it found about 87.6% could stripped from H-AC-Au containing 2.0 kg/t via elution. This study reported new related recovery non-cyanide thiosulfate system, is great significance to gold.
