为了对相山铀矿伴生稀土资源进行有效的经济开发，研究了利用一株全新的具有特异性铀识别能力的微杆菌Microbacterium sp.6-1对相山富稀土铀矿石进行浸出。结果表明：该株微杆菌可定向附着在含铀矿物表面，高效浸出铀元素及伴生稀土元素。在30 d内可浸出原岩约81%铀元素和约62%稀土元素，且能进一步富集浸出液中重稀土元素。研究结果对综合开发铀-稀土伴生矿资源具有重要参考意义。
Abstract：In order to develop Xiangshan uranium-rare earth associated ore economically and effectively, a novel strain of Microbacterium sp.6-1 with specific uranium recognition capability was utilized to conduct the bioleaching experiment on Xiangshan uranium-rare earth associated ore.The results show that a novel strain of Microbacterium sp.6-1 can be directionally attached to the surface of uranium-containing minerals and efficiently leach uranium elements and associated rare earth resources.Around 81% uranium and 62% rare earth elements can be leached from the uranium-rare earth associated ore within 30 d, with a further enrichment of heavy rare earth elements in the leachate.The research results have important reference significance for the comprehensive development of uranium-rare earth associated mineral resources.
