Abstract

The results of MLA automated quantitative mineralogy system indicated the uranium ore used in this study was mainly composed of pitchblende(1.026), aluminosilicate(include biotite(31.72%), albite(13.98%) and orthoclase(13.43%)), and fluorite(0.94%). The fluoride-resistant bacteria strain could growth normally under the condition of fluoride ion concentration as high as 600mg/L. The uranium extration rate of bioleaching flask reached 74% in 10 days, bioleaching have obvious advantages compare to conventional acid leaching (46%).
