Uranium is usually finely disseminated in ore bodies, making leaching the most common process to recover it instead of ore dressing for concentrate production. Many uranium ores processed via bioleaching have contained significant amounts of pyrite and other Fe-sulfides, which are oxidized to acidic ferric sulfate.
