The Critical West: raw materials and rare earths
(Open University Geological Society, 2017-04-20)Critical raw materials are defined as raw materials that are economically important but vulnerable to supply disruption. They are important now because we mine and use a wider range of elements than ever before. Digital ... -
Response to ‘Assessing the energy requirements and global warming potential of the production of rare earth elements’
(Elsevier, 2017-06-10)In this letter, we respond to the article in this journal by Weng et al. (2016) which performs a cradle to gate scale life cycle impact assessment for 26 operating and potential rare earth element (REE) mining projects. ... -
Applying and advancing the economic resource scarcity potential (ESP) method for rare earth elements
(Elsevier, 2018)A number of studies have identified rare earth elements (REE) as critical metals due to their high economic importance combined with a high risk of supply disruption (Du et al, 2011; Nassar et al, 2015; Schneider et ... -
Evolution of South Atlantic density and chemical stratification across the last deglaciation
(National Academy of Sciences, 2016-01-19)Explanations of the glacial-interglacial variations in atmospheric pCO2invoke a significant role for the deep ocean in the storage of CO2. Deep-ocean density stratification has been proposed as a mechanism to promote the ... -
A record of spontaneous subduction initiation in the Izu-Bonin-Mariana arc
(Springer Nature, 2015-08-24)The initiation of tectonic plate subduction into the mantle is poorly understood. If subduction is induced by the push of a distant mid-ocean ridge or subducted slab pull, we expect compression and uplift of the overriding ... -
Financial services for resilience: how to assess the impacts
(BRACED Knowledge Manager, 2017-06-20)key messages • Niger is a least developed country prone to recurrent drought, which affects a large share of the population and results in severe food security issues. • Support mechanisms, including access to adequate ... -
Discerning primary versus diagenetic signals in carbonate carbon and oxygen isotope records: An example from the Permian-Triassic boundary of Iran
(Elsevier for European Association of Geochemistry, 2015-12-29)Sedimentary successions across the Permian-Triassic boundary (PTB) are marked by a prominent negative carbon isotope excursion. This excursion, found in both fossil (e.g., brachiopod) and bulk carbonate at many sites around ... -
Mining and Planetary Health: A GeoHealth-Led Special Collection
(American Geophysical Union, 2018-10-05)Mining is a vital part of the global economy, but unmanaged releases of mine wastes can affect the health of humans, ecosystems, water, soil and Earth surface environments (e.g., rivers and estuaries). New technological ... -
Mine tailings dams: Characteristics, failure, environmental impacts, and remediation
(Elsevier for International Association of GeoChemistry, 2014-10-07)On a global scale demand for the products of the extractive industries is ever increasing. Extraction of the targeted resource results in the concurrent production of a significant volume of waste material, including ... -
Onset of main Phanerozoic marine radiation sparked by emerging Mid Ordovician icehouse
(Springer Nature, 2016-01-06)The Great Ordovician Biodiversification Event (GOBE) was the most rapid and sustained increase in marine Phanerozoic biodiversity. What generated this biotic response across Palaeozoic seascapes is a matter of debate; ... -
Scorodite precipitation in the presence of antimony
(Elsevier for European Association of Geochemistry, 2015-04-27)The effects of Sb on the precipitation of synthetic scorodite, and the resultant phases formed, were investigated. Nine synthetic precipitates with varying concentrations of Sb, together with As-only and Sb-only end members, ... -
The role of nano-sized manganese coatings on bone char in removing arsenic(V) from solution: Implications for permeable reactive barrier technologies
(Elsevier, 2016-03-24)Although the removal of arsenic(V) (As(V)) from solution can be improved by forming metal-bearing coatings on solid media, there has been no research to date examining the relationship between the coating and As(V) sorption ... -
Coupling effect of Fe3+(aq) and biological, nano-sized FeS-coated limestone on the removal of redox-sensitive contaminants (As, Sb and Cr): Implications for in situ passive treatment of acid mine drainage
(Elsevier for International Association of GeoChemistry, 2017-03-11)Nano-sized FeS particles have been shown to improve the adsorption performance in permeable reactive barrier (PRB) technologies that are used to treat acid mine drainage. To investigate the coupling effect of Fe3+and ... -
Geometallurgy: driving innovation in the mining value chain
(AusIMM: Australasian Institute of Mining and Metallurgy, 2016-06-14)Geometallurgy is a discipline which seeks to improve the sustainability of the extraction of metals and minerals by promoting the smarter use of non-renewable resources, better energy efficiency and greater use of renewable ... -
Turbulence model development for flotation cells based on piezoelectric sensor measurements
(Elsevier, 2016-05-20)Turbulence is an important factor that affects flotation performance, which needs to be incorporated into flotation models. However, the measurement of turbulence in industrial flotation cells is difficult because of the ... -
Data-driven model reduction-based nonlinear MPC for large-scale distributed parameter systems
(Elsevier / International Federation of Automatic Control (IFAC), 2015-09-08)Model predictive control (MPC) has been effectively applied in process industries since the 1990s. Models in the form of closed equation sets are normally needed for MPC, but it is often difficult to obtain such formulations ... -
Solid-phase phosphorus speciation in Saharan Bodélé Depression dusts and source sediments
(Elsevier for European Association of Geochemistry, 2014-06-29)Phosphorus (P) is one of the most important limiting nutrients for the growth of oceanic phytoplankton and terrestrial ecosystems, which in turn contributes to CO2sequestration. The solid-phase speciation of P will influence ... -
