It is shown that in dilute nitric acid monohydrate dissolved Mo, Mo and dihydrate nadmolibdenova acid with approximately equal Mo content. Upon dissolution of Mo in the wire dilute nitric acid shows a nearly linear dependence of the dissolution time reducing the weight of the wire. Detected quasi-periodic dependence of the residual content of Mo in the nitric acid solution from the dissolution time. For a description of quasi-periodic in time of Mo dissolution in dilute nitric acid tritrofna proposed a model based on the presence of nitric acid in the solution is about equal proportions molybdic acid of 3 types: N2MoO4; N2MoO4 o H2O; N5MoO6. It is shown that the maximum extraction efficiency Mo reaches 90%. A review of the uranium content in ores from different deposits of the world and contains the estimated cost of its production in Ukraine.
