摘　　要：试验了以氰化搅拌浸出和柱浸从低品位含金尾矿中金。根据试验结果，对湖北蛇屋山金矿尾矿进行了氰化浸金试验研究。对金矿尾矿首先进行制粒，然后以氰化法浸出金。试验结果表明，用碱性溶液预处理8h，氰化钠用量1kg／t，浸出24h，溶液pH为10．0～12．0，金浸出率可达60％以上。Extraction of gold from low-grade gold containing tailings by column leaching are tested. According to column leaching test results, leaching of gold from gold-containing results showed that, gold-containing solution, then was leached for 24 hours tailings from Snake Mountain in tailing palletized was pretreated cyam the Hub for de leaching and stirring ex ei 8 using sodium cyanide solution. Leaching periments on cyanide have been gone. The hours using alkaline rate was over 60% at the conditions of sodium cyanide amount of 1 kg/t and the solution pH of 10.0 to 12.0.
