v117n8a9 Recovery of uranium from nuclear conversion

2017-9-27  Recovery of uranium from nuclear conversion plant waste Murashita, and Nomura (2014) extracted uranium from UF4 residue and NaF adsorbents originating from conversion activities. It thus became clear that this waste material is unique, in terms of its intrinsic variety in composition as well as the amounts and types of impurities present.

ALTA MetBytes - Uranium Ore Processing Still Advancing

2020-1-15  nano-filtration plant to recover and recycle sulphuric acid from uranium IX eluate, believed to be the first commercial operation of its type in the world, was successfully installed and commissioned at Paladin Energy’s Kayelekera Uranium Mine in northern Malawi in 2013. It utilizes technology developed by Paladin Energy and BMS Engineers, Perth, Australia for which Paladin Energy have been granted a patent. The design has successfully demonstrated that a uranium-containing acid stream can be separated into a clean, uranium-depleted, acid stream containing the majority of the acid and a low-volume concentrated uranium stream. Apart from the significant acid savings (circa 40 t/day 98% sulfuric acid), it also resulted in significant savings in downstream neutralizing chemical requirements. A second plant has been designed, installed and commissioned at Langer Heinrich. This plant, designed to recover
