BIOACTIVATION OF LEACHING SOLUTION FOR URANIUM IN-SITU RECOVERY

SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings, 2022
Technology of in-situ recovery (ISR) of uranium is using in Kazakhstan for increasing of production 15 times from 800 ton in 1998 till 22 000 ton in 2013. This ISR process is zero wastes technology. Investigations showed serious potential to improve results of ISR technology using biotechnology methods.
