【摘要】 以浙赣火山岩铀矿床为例,通过铀矿石工艺矿物学和浸矿过程化学作用分析,讨论了原地破碎浸铀过程中,铀及其他金属在硫酸溶液作用下的迁移与富集作用;指出在浸铀过程中可能出现严重影响浸矿效率的地球化学分层问题,并提出利用细菌浸铀和改善布液方式的解决方案。更多还原

【Abstract】 Based on analyzing the technological mineralogy of uranium ore and the chemical action in leaching uranium process,the migration and enrichment of uranium and other metals in stope leaching of uranium were discussed taken volcanic uranium deposits in Zhegan district as an exampleIt was pointed out that the geochemical stratification in leaching uranium process might come into being,which had a great impact on leaching rate of uraniumAn effective solution of utilizing bacteria for leaching uranium and improving liquid distribution system was put forward更多还原
