The solvent extraction of uranium (VI) from aqueous solutions has been investigated using hexadecylhydroxydiphosphonic acid (HHDPA, H 4 L 1) and dodecylhydroxydiphosphonic acid (DHDPA, H 4 L 2), which were synthesized and characterized by elemental analysis and by FT-IR, 1 H NMR, 31 P NMR spectroscopy. In this study, we propose a tentative assignment for the shifts of those two ligands
25-10-2020· Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.

A process is claimed for the extraction of uranium from ores which is an improvement in the known dry attack treatment of uranium ores to an economical yet high rate of extraction. The process concerns solubilization of the uranium contained in the ores and consists of carrying out digestion of the mixtures of ore and reagent, with the possible
