Bacterial leaching the biooxidation of metal sulfides to soluble metal sulfates and sulfuric acid is effected by specialized bacteria Three species of mesoacidophilic chemolithotrophic bacteria are mainly involved Thiobacillus ferrooxidans Thiobacillus thiooxidans and Leptospirillum ferrooxidans12 Microbial Leaching of Uranium Ore Hadi Hamidian Islamic Azad University Qaemshahr Branch Iran 1 Introduction This chapter is a review of the microbiological leaching of uranium or

The principle of the method lies in leaching the uranium ore with ferric sul phate produced from the pyrite of the ore by bacterial action and which in turn can be regenerated by the bacteria Fig 4 Bacterial leaching of uranium ore from Figueira—PR Brazil Abstract A bacterial leaching program was carried out in order to evaluate the potential of applying this process to leach uranium from the ore of Figueira PR Brazil Chat online

application to raw material supply microbial leaching has some potential for remediation of mining sites treatment of waste and detoxification of dump/sludge Commercial application of bioleaching the microbially assisted leaching of uranium ore is by direct or indirect mechanism In the leaching of uranium the bacteria do not directly In this paper a continued column bioleaching system has been established for leaching a certain uranium ore which contains high fluoride The analysis of chemical composition of ore shows that the grade of uranium is x25 which is lower than that of other deposits
