Abstract

Process mineralogy of a uranium ore which had U (0.22%) and F (1.04%) was investigated by modern SEM-based mineral liberation analysis (MLA) system and traditional process mineralogy research methods. The results indicate that traces of uranium minerals are mainly pitchblende, small amount of coffinite and brannerite in this ore. Pitchblende, coffinite and brannerite are fine and mainly embedded in quartz, muscovite and calcite. The content of pyrite and fluorite are 0.436% and 2.177% respectively. Fluorine minerals are mainly fluorite which is harmful to bioleaching. The content of quartz is 64.9%, which is the main gangue in this ore. The characteristic of this ore is low content and fine particle size of pitchblende, low sulfide and high fluorine. Bioleaching won't have obvious advantages compare with conventional acid-leaching.
