摘要
常压下用水从改性白云石中浸出铷和铯,考察了温度、浸出时间、液固比、浸出液循环使用次数对铷铯浸出率的影响。试验结果表明:改性白云石加入水中,在浸出温度40℃、浸出时间120 min、液固比3∶1、浸出液循环次数为3次时,铷和铯浸出率分别为95.13%和96.00%,浸出效果较好。
The modified dolomite was leached with water at normal atmosphere. The influences of temperature, leaching time and liquid/solid ratio, as well as recycling times of leaching liquor on leaching of rubidium and cesium from modified dolomite were explored. It is found that with the modified dolomite in the water at a liquid/solid ratio of 3 ： 1, leaching at 40°C for 120 min, with the leaching liquor recycled for three times, the leaching rate of rubidium and cesium reached 95.13% and 96.00%, respectively.
