In situ leaching and recovery of uranium from are deposits
Creators
Description
The invention relates to the recovery of uranium from underground ore deposits by in-situ leaching and the subsequent processing of the enriched leaching solution to recover relatively pure uranium compounds. The leach solution is adjusted to a pH of 7.4 to 9 and comprises essentially 0.5 to 5 grams per liter of ammonium bicarbonate and 0.1 to 3 grams per liter of hydrogen peroxide, the peroxide being added to the leach solution just before it comes into contact with the ore. The leaching solutions employed cause no material deterioration or contamination of the underground deposits or any acquifer associated with the ore deposit. Furthermore, the process produces above the ground surface a very low volume of impurities and waste solution requiring disposal. (J.R.)
