| 摘 要： | 硼精矿碳碱法浸取过程中，硼精矿中的微量铀同时也被浸取．在保证硼的浸取率较高的情况下，研究对铀的浸取率的影响因素．结果表明：①氧化焙烧温度影响铀的价态．②铀的浸取率随减量的增加而增加．③铀的浸取率随着氧化剂的增加而增加．④硼精矿粒度越细，铀的浸取率越高．

| Abstract: | The uraninm in boron-concentrate is leached when the boron is leached. The processing condition of leaching of uranium were investigated during the boron in boron-concentrate was leashed. The results are showed as follow:1.Roast in air changes valence of uranium.2. Alkalinity has influence on leaching rate of uranium.3. Oxygenant affects leaching rate of uranium.4. Concentrate size effects the leaching rate of uraninm because uranium in concentrate is covered with another mineral. |
