Bioleaching of a Uranium Ore from Xiangshan Deposit and its Associated Rare Earth Resources
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.
