  "term": "In situ leach",
  "field": "Nuclear energy and radiation",
  "definition": "A process using a solution called lixiviant to extract uranium from underground ore bodies in place (in other words, in situ). Lixiviant, which typically contains an oxidant such as oxygen and/or hydrogen peroxide mixed with sodium carbonate or carbon dioxide, is injected through wells into the ore body in a confined aquifer to dissolve the uranium. This solution is then pumped via other wells to the surface for processing. For additional detail, see In Situ Recovery Facilities.",
