ABSTRACT:
In a process for the solution mining of a uranium ore formation using an aqueous alkaline carbonate leaching solution containing hydrogen peroxide as oxidant, the solution is passed through the ore formation in the presence of an alkylidene-1,1-diphosphonic acid. Such an acid has been found to be unique in its capability for stabilizing the peroxide against decomposition in the presence of the uranium ore.
