新疆某铀矿床淡化地下水碱法地浸试验研究
Alkaline in-situ leaching simulation test of a uranium deposit in Xinjiang under condition of diluting groundwater
摘要
Abstract
The reagents used in in-situ leaching of uranium include NH4HCO3 and dissolved oxygen after groundwater is diluted. The relation between the reagent concentration and leaching effect is studied under condition of diluting groundwater. The results show that uranium concentration in lixivium and leaching rate are closely related to HCO-3 concentration. There are optimal value of HCO-3 and liminal value of HCO-3 during leaching uranium. The optimal technology parameter of HCO-3 concentration can be decided according the values. The more dissolved oxygen in the leaching system, the better leaching effect of uranium. So, it is a key technology for improving leaching effect of uranium to increase dissolved oxygen concentration. But the HCO-3 concentration is controlled by the condition which causes precipitation of CaCO3, and has connection with pH and Ca2+ concentration.关键词
