金矿氰化浸出助浸剂的研究

Study on the Leaching Aids of Gold Ore Cyanidation-Leaching

介绍了柠檬酸作氰化浸出助浸剂 ,分别对罗山金矿浮选精矿、鹿尔坝金矿焙砂、鹰嘴山北金矿进行助浸试验的结果。研究结果表明 ,柠檬酸作为助浸剂可改善氰化浸出环境 ,提高浸出速度 ,缩短氰化浸出时间 ,降低氰化物用量。

The results of tests using citric acid as the leaching aid for cyanidation leaching on the flotation concentrate of Luoshan Gold Mine,the burnt ore of Luerba Gold Mine and the ore of Yingzuishan Gold Mine are described.The study shows that using citric acid as the leaching aid can improve the cyanidation leaching environment,raise the leaching speed,reduce the cyanidation leaching time and decrease the cyanide consumption.
