中文摘要: 考察了氧化锌矿的粒度、浸出温度、浸出时间、碱浓度及液固比对碱浸出高硅难选氧化锌矿中Zn及伴生金属浸出率的影响.结果表明:氧化锌矿粒级对Zn及伴生金属浸出率影响不大;随着碱浓度的增加,Zn、Al浸出率增加明显,Pb、Cd浸出率增加缓慢,Fe基本不被浸出;随着浸出温度的提高,Zn的浸出率大幅度增加,温度从25℃升高到85℃,浸出率增加了近50个百分点,Al的浸出率在25～60℃范围内增加缓慢,基本保持在20%附近;当温度从60℃升高到85℃时,Al的浸出率也由22.3%大幅度增加到45.5%;随着浸出时间的延长,Zn和Al的浸出率增加,但是增加缓慢,Pb、Cd的浸出率没有太大的变化.液固比从6:1增加至12:1,Zn、Al、Pb、Cd浸出率均有增加.
Abstract:Effect factors,such as ore size,leaching temperature,leaching time,alkali concentration and liquor to solid ratio(L/S),were studied to check the impact of leaching efficiency of zinc and its concomitant metals from zinc oxide ore with high silicon in the alkali solution.The results show that ore size affected little on it.With the increasing of alkali concentration,leaching efficiency of zinc and aluminium increased remarkably,but that of Pb and Cd increased slowly and Fe can't almost be leached.With the in...
