uranium ore processing concentrate leaching The hydrometallurgical processing of uranium ores is frequently preceded by a high-temperature calcination step. Roasting dehydrates the clay content of many ores, removes carbonaceous materials, oxidizes sulfur compounds to innocuous sulfates, and oxidizes any other reductants that may interfere in subsequent leaching operations

The leach liquors pass through the ore to oxidise and dissolve the uranium minerals in situ. Depending on the type of leaching environment used the uranium will be complexed as either a uranyl sulphate, predominantly UO 2 (SO 4) 3 4-, in acid leach conditions or a uranyl carbonate, predominantly UO 2 (CO 3) 3 4-in a carbonate leach system.

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
