摘要
优化条件试验表明,对原生程度高的矿石,浸出工艺条件的变化对金浸出率影响不大,但采用边磨边金浸工艺,可提高金浸出率3.5%。对原生程度低的矿石,即现生产矿石,影响金浸出率主要因素为磨矿细度和氰化钠用量。
The leaching optimum test indicates that the changes of leaching technological conditions will not influence recovery rate of gold of non-oxidized ore. A process of grinding simultaneously with leaching contributed to an increase of gold leaching rate by 3.5%. The grinding fineness and concentration of sodium cyanide are main factors that influence gold leaching rate of incomplete oxidation ore.
