Acid and ferric sulfate bioleaching of uranium ores: A review
Livesey-Goldblatt et al. (1977) developed a pilot-plant unit for the continuous oxidation of recycled ferrous sulfate leach solution from a uranium ore processing plant. The process was called BACFOX, and utilized iron-oxidizing Acidithiobacillus ferrooxidans bacteria, which were retained as a film on corrugated packing media.
