| 摘 要： | 对堆浸前矿石的破碎分级中的泥矿和高品位精矿进行了搅拌浸出工艺的实验室试验研究和现场验证试验。泥矿酸法搅拌浸出铀浸出率达到96%以上。高品位矿石碳酸盐含量高,酸法浸出铀浸出率可达99%以上,但是酸耗高;而碱法浸出高品位矿石时,在常温条件下浸出率不到70%,提高浸出温度可显著提高浸出率。使用压滤机进行固液分离是可行的,其矿石处理能力可达到155 kg/(m2.d),洗涤效率达99%以上。

| Abstract: | Lab experiment and field pilot test were conducted on a slurry from the ore crushing and classification process prior to heap leaching and on a high grade concentrate through ore separation.96% of uranium extraction can be reached for the slurry ore applying acid leaching.99% of uranium can be extracted for the concentrate by acid leaching,with the acid consumption being quite high as considerable carbonate associated with the concentrate.While alkaline leaching was applied to the concentrate,only 70% of ur... |
