摘要
介绍了采用“添加剂预处理—氰化浸出—锌粉置换”工艺从某浮选金精矿中提金的试验结果，主要考察了磨矿细度、添加剂用量、时间对预处理效果的影响，在合理工艺条件下氰化浸金率大于９６％。
The experimental result for gold extraction from a concentrate by 'pretreatment-cyanide leaching-zinc dust cementation' is introduced.Influences of grinding fineness,additives' quantity and operation time on pretreatment effect were investigated.Gold leaching rate of above 96% for the concentrate can be obtained under optimum process condition.
