Although recent studies have detected elevated concentrations of arsenic and uranium in inland, alkaline, saline lakes, the chemical reactions associated with these enrichments are poorly understood. In this study, we used a five-year study of water chemistry, characterization of arsenic and...

Incorporating uranium into magnetite crystal from wastewater to limit its mobility have been proposed to the long-term remediation of radioactive contamination. Unfortunately, this process is accompanied by reduction or surface adsorption, which significantly reduces the incorporation capacity...

Kayelekera uranium mine is the biggest mining project in Malawi’s history and began production in 2009. In 2013, revenues from the mine contributed 2.6% to Gross Domestic Product. Yet production at Kayelekera was suspended as a result of the crash in uranium prices following the Fukushima...

Mining and smelting of vanadium uranium ore results in the release and coexistence of vanadium and uranium in the environment, raising severe risks. The feasibility of synchronous removal of pentavalent vanadium (V(V)) and hexavalent uranium (U(VI)) was investigated in mixotrophic column reactor...

Uranium extraction from seawater has attracted increasing attentions for nuclear raw material to support the sustainable development of nuclear power plants. However, it is still a grand challenge to overcome the high salinity background and ultra-low uranyl concentration. Herein, we...

Uranyl, a strong Lewis acid, forms stable complexes with relatively hard donors and it is commonly believed that uranyl complex with trialkylamine is stabler than trialkylphosphine. However, there are no thermodynamic parameters to evaluate the complexation stabilities of R 3 N-UO 2 2+ and R 3...

Following the accident at the Fukushima Daiichi Nuclear Power Plant, many countries began funding research and development on nuclear fuel designs with enhanced accident tolerance (ATFs). ATFs have improved designs, materials and performance features compared with those of the current generation...

The transformative activity of mining has numerous economic, social and environmental impacts that can be both positive and adverse for communities, ecosystems and economies. As the uranium industry begins to address negative perceptions and legacies associated with past activities,...
