Natural uranium as found in the Earth's crust is a mixture largely of two isotopes: uranium-238 (U-238), accounting for 99.3% and uranium-235 (U-235) about 0.7%. The isotope U-235 is important because under certain conditions it can readily be split, yielding a lot of energy.

Mar 18, 2021 Uranium ores typically have very low yields of the element of between 0.1 to 0.2%, and some have concentrations lower than 0.05%. The Canadian Saskatchewan mines are the exception and have yields of more than 20% uranium. However, flooding and environmental concerns make the future of mining in this region uncertain.

the present process provides an alternative to the diluteacid process for recovering uranium values from refractory ores. instead of fine-griding the ore, it is comminuted to a relatively large top size (not substantially smaller than 1 mm) and mixed with sufficient sulphuric acid of relatively strong concentration suitablyy about 6,n, to wet the ore without forming a continous liquid phase.
