Bioleaching - Wikipedia

Bioleaching of non-sulfidic ores such as pitchblende also uses ferric iron as an oxidant (eg, UO 2 + 2 Fe 3+ ==>UO 2 2+ + 2 Fe 2+) In this case, the sole purpose of the bacterial step is the regeneration of Fe 3+ Sulfidic iron ores can be added to speed up the process and provide a source of...
