Uranium: Where Is It?

It can be found in minute quantities in most rocks, soils and waters (normally < 5 ppm), but the real challenge is to find it in high enough concentrations to make it economically feasible to mine. Uranium is easily oxidized and forms a number of common uranium oxides and oxy-hydroxide like uraninite (or pitchblende) and schoepite (including meta- and para-).
