Patent
In situ uranium leaching using high pressure CO2/O2 system to overcome chloride ion inhibition
Creators
Description
A process is described for improving yield and leaching rates of mineral values in uranium-bearing formations associated with high brine aquifers by using high pressure CO2/oxidant in the leaching solution. The high pressure CO2 overcomes the inhibiting effect of NaCl on the rate of leaching. Uranium is recovered at the well head by ion exchange at a pH of about 4.5 to about 5.0 either under pressure to keep the CO2 in solution or with provision for CO2 recovery and recycle
