A technology that has not been considered thus far is the tank bioleaching of uranium concentrates. In the 1990s, Mintek undertook extensive research into the bioleaching of typical Witwatersrand uranium- and gold-bearing ores and concentrates. It was found that the low temperature of the bioleaching process, which was restricted to 35 °C, resulted in such slow uranium extraction rates that

Processes which have been used for leaching uranium involve either acidic or basic leaching means. The common means employed in treating most North American lean uranium ores involves leaching with sulfuric acid along with an oxidizing agent which may be, for example, manganese dioxide, oxygen or sodium chlorate.
