The Daxin Uranium Mine was a small open pit mine with contaminated facilities that included an open pit of 87,620 m2, east waste rock pile of 71,710 m2, west waste rock pile of 57,828 m2, ore transfer station and industrial fields of 9,370 m2, building and structures of 26,600 m2, 246 pieces of equipment, 3000 m of plastic conduit. 2500 m of steel conduit and 1020 m of roads used for transport uranium ores. We present the integrated decommissioning programme utilized to closeout this uranium mine: uranium extraction, slope stabilization, cleanup, backfill, reshaping and covering, re-vegetation, dismantlement and demolishment of facilities, decontamination, re-smelting and wastewater treatment.
