It is difficult to loss uranium today; but if it is lost or stolen should be of course sought !
Uranium becomes lead
you get wet uranium
Uranium was created in the early stages of the universe by stellar nucleosynthesis. Uranium cannot be lost from the earth.
For example, metallic uranium is soluble in nitric acid.
Uranium is not necessary for the organism of any living form.
Uranium doesn't react with copper.
Who will do that ? The result leads to nothing.
At room temperature - nothing.
Ask Duane Parnham, google him.
Repeat step 3
Uranium ores are transformed in uranismoctoxide, uranium metal, uranium dioxide, ammonium diuranate, uranium tetrafluoride, uranium hexafluoride etc. Another step is to prepare uranium alloys, uranium dioxide sintered pellets, enriched uranium - in other plants.
Uranium don't react with water at room temperature; strontium react with water and the hydroxide Sr(OH)2 is formed.
