METHOD FOR SEPARATING IRON FROM AN ORGANIC PHASE CONTAINING URANIUM AND METHOD FOR EXTRACTING URANIUM FROM AN AQUEOUS SOLUTION OF MINERAL ACID CONTAINING URANIUM AND IRON

摘要

The invention relates to a method for separating iron from an initial liquid organic phase containing uranium and iron, in which the initial liquid organic phase is placed in contact with an aqueous solution referred to as aqueous iron-removal solution, by means of which the iron passes into the aqueous solution in order to form a final liquid aqueous phase, and the uranium remains in the initial liquid organic phase in order to form a final liquid organic phase referred to as iron-removed organic phase; said method being characterised in that the aqueous iron-removal solution contains an inorganic acid and uranium, and does not contain iron. The invention also relates to a method for extracting uranium from an aqueous solution of an inorganic acid containing uranium and iron.
