The hydrometallurgical process developed by the Company is capable of producing high purity electrolytic manganese dioxide (EMD) and chemical manganese dioxide (CMD), both of .
As noted in Figure 6, the solvent extraction process differs from the dry hydrofluor process in that uranium concentrate is initially digested in hot nitric acid. Solvent extraction is then used for purification, with tributyl phosphate in hexane as the organic phase and water as the second extractant.

Uranium is a chemical element with symbol U and atomic number 92. It is a silverygrey metal in the actinide series of the periodic uranium atom has 92 protons and 92 electrons, of which 6 are valence is weakly radioactive because all isotopes of uranium are unstable, with halflives varying between 159,200 years and billion years.

Expensive manganese concentrate is used as an oxidant during the agitation uranium leaching. Decreasing of consumption of this concentrate or its replacement by another reagent is an urgent task.
Rhees found that other oxidants such as sodium chlorate and manganese dioxide were ineffective in dissolving UO2 except in the presence of iron. Thus most of the research concerning the oxidation of tetravalent uranium in acid solutions has focused on the use of Fe(III) as the oxidant.
Bakier2, The characterization of the new sorbent impregnated by nano manganese and G. A. AlMagid2 1 dioxide was performed by scanning electron microscope, transmission elec Egyptian Nuclear and tron microscope, energydispersive Xray, Xray diffraction, and Fourier Radiological Regulatory transformation infrared spectrometric analyses.
