Abstract: Uranium is generally associated with the gold ores of the Witwatersrand, at times at concentrations which may be economically viable for extraction as a by-product to the gold. Uranium and its radiogenic progeny are therefore found in many of the residues and wastes produced in the mining and processing of Witwatersrand ores.
