Boron recovery from desalination seawater brines by selective ion exchange resins
(Elsevier, 2022-07-15)
Article
Open AccessThe European Union (EU) depends on third markets to supply many important raw materials. Increasing the circularity of critical raw materials within the EU is important not only from an environmental perspective, but also ... -
Development of novel techniques of advanced transport characterization of membranes
(Universitat Politècnica de Catalunya, 2020-10-01)
Doctoral thesis
Open AccessOptimization of membrane separation processes rely on the accurate determination of some parameters related to membrane structure, chemistry, morphology or transport mechanism. Therefore, membrane characterization is ... -
Evaluation of the purity of magnesium hydroxide recovered from saltwork bitterns
(2023-01-01)
Article
Open AccessMagnesium has been listed among the 30 critical raw materials by the European Union. In recent years, many green and sustainable alternative Mg2+ sources have been sought to satisfy the EU’s demand and to avoid mineral ore ... -
Implications of inhomogeneous distribution of concentration polarization for interpretation of pressure-driven
(2016-08-22)
Article
Open AccessA number of CFD studies have demonstrated that there is a considerable inhomogeneity of extent of Concentration Polarization (CP) over the membrane surface especially in spacer-filled feed channels. However, the consequences ... -
Increasing the circularity of the copper metallurgical industry: Recovery of Sb(III) and Bi(III) from hydrochloric solutions by integration of solvating organophosphorous extractants and selective precipitation
(2023-02-01)
Article
Open AccessThe lack of high-purity ores has made the copper industry exploit low-impurity ores containing As, Sb and Bi which can affect the final product quality due to the floating insoluble arsenates. This is usually solved by ... -
Influence of membrane sealing in pressure-driven test cells on their performance
(2019-01-01)
Article
Open AccessThis communication demonstrates the relevance of membrane sealing in a test cell to its performance. Membranes need to be sealed, and therefore a more or less significant (depending on the test cell design) peripheral part ... -
Mining minerals and critical raw materials from bittern: Understanding metal ions fate in saltwork ponds
(Elsevier, 2022-11)
Article
Open AccessSeawater represents a potential resource for raw materials extraction. Although NaCl is the most representative mineral extracted other valuable compounds such as Mg, Li, Sr, Rb and B and elements at trace level (Cs, Co, ... -
Nanofiltration of multi-ion solutions: Quantitative control of concentration polarization and interpretation by solution-diffusion-electro-migration model
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-04-01)
Article
Open AccessFor effective use of advanced engineering models of nanofiltration quality of experimental input is crucial, especially in electrolyte mixtures where simultaneous rejections of various ions may be very different. In ... -
Polymeric and inorganic sorbents as a green option to recover critical raw materials at trace levels from sea saltwork bitterns
(Royal Society of Chemistry (RSC), 2023-01-01)
Article
Open AccessSeawater mining is certainly a green alternative source for obtaining minerals as seawater is a natural renewable and unlimited available resource. Based on the lack of ways to obtain certain raw materials, the European ... -
Reclamation of urban pollution impacted groundwater by advanced treatment processes: Effect of prechlorination on the removal of metals, ammonium and NOM at pilot scale
(2023-08)
Article
Open AccessThe need for new water resources in water scarcity regions has driven the exploration of water reclamation through a variety of treatment technologies. The present study aims at reclaiming impacted urban groundwater through ... -
Recovery of antimony and bismuth from arsenic-containing waste streams from the copper electrorefining circuit: An example of promoting critical metals circularity from secondary resources
(Elsevier, 2023-08)
Article
Open AccessThe copper pyrometallurgical industry faces the precipitation of un-soluble slimes containing bismuth, arsenic and antimony that can reduce copper purity. Ion-exchange resins are used to treat the electrolyte to avoid their ... -
Recovery of lithium carbonate from dilute Li-Rich brine via homogenous and heterogeneous precipitation
(American Chemical Society (ACS), 2022-08-30)
Article
Open AccessAn extensive experimental campaign on Li recovery from relatively dilute LiCl solutions (i.e., Li+ ~ 4000 ppm) is presented to identify the best operating conditions for a Li2CO3 crystallization unit. Lithium is currently ... -
Selective recovery of boron, cobalt, gallium and germanium from seawater solar saltworks brines using N-methylglucamine sorbents: column operation performance
(Elsevier, 2024-05)
Article
Open AccessThe European Union (EU) identified a list of Critical Raw Materials (CRMs) crucial for its economy, aiming to find alternative sources. Seawater is a promising option as it contains almost all elements, although most at ... -
Sustainable recovery of critical elements from seawater saltworks bitterns by integration of high selective sorbents and reactive precipitation and crystallisation: Developing the probe of concept with on-site produced chemicals and energy
(2023-02-15)
Article
Open AccessThe availability of raw mineral resources containing elements included in the Critical Raw Materials (CRMs) list is a growing concern for the European Union. Sea mining has been identified as a promising secondary source. ... -
Transient membrane potential after concentration step: A new method for advanced characterization of ion-exchange membranes
(2019-09-01)
Article
Open AccessA better understanding of ion-transport mechanisms requires separate information on the equilibrium (partitioning) and kinetic (diffusivity) properties of the membranes with respect to ions. This work presents a novel ... -
Unlocking hidden mineral resources: Characterization and potential of bitterns as alternative sources of critical raw materials
(Elsevier, 2024-01-10)
Article
Open AccessMineral extraction from seawater brines has emerged as a viable solution to reduce Europe's reliance on imported Critical Raw Materials (CRM). However, the economic viability of this approach hinges on the local demand for ...
