FIELD: metal extraction when decontaminating and recovering radioactive waste by way of extraction in supercritical or liquefied gases.
SUBSTANCE: metals are extracted using extraction agent solution in environment of supercritical fluid or liquefied gas. Re-extraction is conducted by passing supercritical fluid or liquefied gas incorporating metal complexes through solid re-extraction agent containing system. Then supercritical fluid or liquefied gas containing recovered extraction agent is returned to process origin.
EFFECT: ability of conducting multiple re-extraction using same amount of extraction agents by recovering extraction agent without pressure reduction.
