#criticalrawmaterials

Hi all. I’m bored. I’m not really “back” - still have super bad writer’s block/no time - but I’ve realized I need conversation that’s not just “lol Instagram reel.” So hello, people of Mastodon. I am doing a PhD in #PoliSci (#geoeconomics/#CriticalRawMaterials). I work on the #EnergyTransition and often go to energy conferences and similar, most recently at DGAP and one held by adelphi. I live in Germany (mein Deustch ist C1 aber nicht perfekt) . Photography is my thing. Hallo! #introduction

⚙️ My latest preprint presents a thermodynamic rationale for a two-stage cascade Eutectic Freeze Crystallization (EFC) process, developed for the treatment and resource recovery of hypersaline mine water from the Svystunova Gully impoundment (published in Ukrainian). ☝️ Key highlights: 🔹 Selective phase separation: Conducting the process in two stages with inter-stage solids separation at -20.0°C provides a 2.5°C operating buffer before chloride salts begin to precipitate, ensuring clean separation of sulfate and chloride fractions. 🔹 High water recovery: The total yield of desalinated water (as pure ice) reaches 964.07 g per 1 kg of initial H2O (96.4% recovery rate). 🔹 Effluent minimization: The initial wastewater volume is reduced 62-fold, concentrating the residual components into a compact, heavy bittern. 🔗 Full preprint: https://doi.org/10.5281/zenodo.22821616 #MineWater #WaterTreatment #Geochemistry #Thermodynamics #PHREEQC #EFC #Mining #CriticalRawMaterials #CircularEconomy #SvystunovaGully #KryvyiRihBasin #FREZCHEM
