中文摘要: 用10 g/L盐酸(pH 0.56)溶液浸泡某碱性铀矿,通过控制不同浸出液的pH,考察参数对碳酸钙浸出率的影响。结果表明,当浸出液pH分别为3、4、5时,碳酸钙的浸出率分别为86.91%、87.65%和81.99%,耗酸率分别为5.11%、4.60%和4.66%,浸出液最佳pH为4。
Abstract:An alkaline uranium ore was leached with 10 g/L hydrochloric acid solution (pH=0.56). The effects of parameters on leaching rate of calcium carbonate were investigated with different pH value of lixivium. The results show that when pH value of lixivium is 3, 4, 5 respectively, the according leaching rate of calcium carbonate is 86.91%, 87.65% and 81.99%, the according acid consumption rate is 5.11%, 4.60% and 4.66%. The optimum pH value of lixivium is 4.
