【摘要】：考察了高嶺土、綠泥石、白云石和褐鐵礦4種常見易泥化礦物對(duì)氰化浸出過程的影響,發(fā)現(xiàn)褐鐵礦和白云石在細(xì)磨時(shí)形成的次生礦泥比原生礦泥具有更強(qiáng)的吸附已溶金能力,使浸出率降低。研究了原礦經(jīng)粗磨-磁選后易泥化礦物的分布,對(duì)云南某金鐵氧化礦采用"粗磨-分類磁選-分組氰化浸出"的新工藝,有效減少了次生礦泥的生成,與"細(xì)磨-氰化浸出-磁選"的傳統(tǒng)工藝相比,金浸出率由85.26%提高到93.05%,鐵精礦回收率由41.20%提高到70.86%。
[Abstract]:The effects of kaolin, chlorite, dolomite and limonite on cyanide leaching process were investigated. It was found that the secondary slime formed by limonite and dolomite had stronger ability to adsorb dissolved gold than primary slime. The leaching rate is reduced. The distribution of easy muddy minerals after rough grinding and magnetic separation of raw ore is studied. A new process of "rough grinding, classified magnetic separation and grouping cyanide leaching" is adopted for a gold and iron oxide ore in Yunnan Province, which effectively reduces the formation of secondary slime. Compared with the traditional process of "fine grinding-cyanide leaching-magnetic separation", the leaching rate of gold is increased from 85.26% to 93.05%, and the recovery rate of iron concentrate is increased from 41.20% to 70.86%.
