Two alternative process routes for recovering pure indium from waste liquid crystal display panels
(Elsevier, 2019-09-25)
Recovering indium from liquid crystal display (LCD) screen waste is important from a sustainability point of view for several reasons: the environmentally hazardous metals are not landfilled, the recovery process involves ...
Design of bypass-simulated moving bed chromatography for reduced purity requirements
(Elsevier, 2019-05-08)
Bypass-Simulated moving bed (BP-SMB) chromatography, a process characterized by the possibility of over-purifying the raffinate and/or the extract product followed by blending with the feed, is studied. The BP-SMB provides ...
Recovering rare earth elements from phosphogypsum using a resin-in-leach process: Selection of resin, leaching agent, and eluent
(Elsevier, 2019-08-10)
Phosphogypsum (PG) is an attractive secondary raw material for rare earth elements (REEs) because it is abundant and contains significant amounts of REEs. Herein, the resin-in-leach (RIL) process for REE recovery from PG ...
Anthocyanin-rich extract from purple potatoes decreases postprandial glycemic response and affects inflammation markers in healthy men
(Elsevier, 2019-10-26)
Our recent clinical study suggested that polyphenol-rich purple potatoes lowered postprandial glycemia and insulinemia compared to yellow potatoes. Here, 17 healthy male volunteers consumed yellow potatoes with or without ...
Modeling the liquid-liquid extraction equilibrium of iron (III) with hydroxyoxime extractant and equilibrium-based simulation of counter-current copper extraction circuits
(Elsevier, 2018)
The phase equilibrium in the loading and stripping stages of the liquid–liquid extraction of iron (III) with hydroxyoxime extractant in kerosene was studied over a wide range of hydroxyoxime extractant (Acorga M5640, 3–25 ...
Synthesis of hydrometallurgical processes for valorization of secondary raw materials using ant colony optimization and key performance indicators
(Elsevier, 2015-02-16)
An algorithm-based method for synthesis of hydrometallurgical processes using limited amounts of experimental data is presented. The method enables simultaneous selection and sequencing of unit operations and optimization ...
Ion exchange in complexing media – Nickel removal from ammoniacal ammonium sulfate solutions
(Elsevier, 2019-05-20)
In real hydrometallurgical systems, ion exchange of metal cations is often accompanied by competing processes, such as complex formation. In this paper, we have analyzed influence of complex formation on nickel uptake in ...
Modeling the phase equilibrium in liquid-liquid extraction of copper over a wide range of copper and hydroxyoxime extractant concentrations
(Elsevier, 2017)
The phase equilibrium in the loading and stripping stages of liquid–liquid extraction of copper with hydroxyoxime extractant in kerosene was studied over a wide range of Acorga M5640 extractant (5–25 vol%) and copper (1–45 ...
Novel mechanical pre-treatment methods for effective indium recovery from end-of-life liquid-crystal display panels
(Elsevier, 2019-05-15)
This study investigated the suitability of mechanical pre-treatment methods (mechanical abrasion and treatments of heat, laser, and plasma) together with a hydrometallurgical process comprising leaching and cementation for ...
Removal and recovery of arsenic from concentrated sulfuric acid by solvent extraction
(Elsevier, 2019-05-13)
Arsenic-contaminated sulfuric acid solutions are produced in large quantities as by-product during pyrometallurgical processing of sulfide minerals. Options for re-using such acid solutions are increased if the arsenic is ...
