Abstract: The column chemical leaching and bioleaching methods recovery of uranium from one uranium ore containing brannerite under the some conditons were investigated. The brannerite ore sample taken from one uranium mine in southern China, the ore particle size was crushed to -5mm, the uranium content is 0.281%. The leaching duration lasted 120 days, the acid consumption rate were 7.82% and 7.79% by ore weight, the slag uranium leaching rate were 89.32% and 91.46% that calculated by its residue has been recovered. This work has indicated that column bioleaching can enhance 2.14% uranium recovery percentage than chemical oxidation leaching, bioleaching be the promising method for uranium extraction from refractory brannerite ore in the deposit.
