摘　　要：矿石中的金常用氰化物和非氰化物作为浸出剂,形成金络合物浸出到浸出液中。由于活性炭具有耐腐蚀、较强的吸附能力、可循环利用等优点,常用来吸附回收浸出液中金络合物。本文在前人研究的基础上,重点分析了氰化炭浆法中活性炭吸附Au(CN)2-的机理和研究进展,概述了非氰浸出液(硫代硫酸盐浸出液、硫脲浸出液、卤素浸出液、硫氰酸盐浸出液)中活性炭吸附回收金络合物的机理及研究进展。为活性炭在提金工业中的更好应用提供参考。Gold and cyanide in ores are used as leaching agents, and gold complexes are leached into leaching fluids. As the active carbon has the advantages of corrosion resistance, strong adsorption ability, recycle and so on, it is commonly used to adsorb the gold complexes. On the basis of previous studies, the mechanism and progress of the adsorption of Au(CN)2 -by activated carbon in cyanide-carbon slurry method are emphatically analyzed. The mechanism and research progress of non-cyanide leaching solution (thiosulfate leaching solution, Thiourea leaching solution, halogen leaching solution and thiocyanate leaching solution) were summarized. It provides reference for better application of activated carbon in gold extraction industry.
