结合某地浸资源的铀矿床室内碱法试验,进行了氧化剂的种类、质量浓度和溶浸剂的种类、质量浓度选择试验,并研究了反应时间铀浸出率的影响。结果表明,碳酸(碳酸氢)钠盐或铵盐是良好的溶浸剂,铀浸出率可达到80%;氧化剂质量浓度为1.0g/L双氧水可满足铀浸出需求。
In combination with a ground-sourced uranium deposit in an indoor alkaline test, the types and concentrations of oxidants and the types and concentrations of oxidants were studied. The effects of reaction time on the leaching rate of uranium were also studied. The results showed that the sodium bicarbonate or ammonium bicarbonate was a good leaching agent with the leaching rate of uranium reaching 80% and the oxidant concentration of 1.0g / L hydrogen peroxide meeting the requirement of uranium leaching.
