Bærekraftig Gjenvinning av Metaller fra Manganslam via Syreleaching
Eini, Ariel Skaug.; Pedersen, Markus Antonius Elinsønn. (Bachelor thesis, 2022)I oppgaven ble effekten av ulike forsøksparametere på metallutbyttet fra leaching av manganslam undersøkt. Det ble gjort ved å syreleache 13 prøver hvor noen av parameterne ble holdt like og noen ble variert. Tre forskjellige ... -
The Effect of Process Conditions on Sulfuric Acid Leaching of Manganese Sludge
Safarian, Jafar; Eini, Ariel Skaug; Pedersen, Markus Antonius Elinsønn; Haghdani, Shokouh (Peer reviewed; Journal article, 2023)Manganese sludge, an industrial waste product in the ferroalloy industry, contains various components and holds significant importance for sustainable development through its valorization. This study focuses on characterizing ... -
A Raman-Structure Model for the Viscosity of SiO2- CaO-Al2O3 System
Haghdani, Shokouh; Tangstad, Merete; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2022)The relationship between structure and viscosity of molten slags is investigated using the Raman spectroscopy technique. To this end, a group of 20 synthetic slags in the SiO2-CaO-Al2O3 ternary system is considered. The ... -
Slag Properties in the Primary Production Process of Mn-Ferroalloys
Tangstad, Merete; Bublik, Sergey; Haghdani, Shokouh; Einarsrud, Kristian Etienne; Tang, Kai (Peer reviewed; Journal article, 2021)The present study has investigated the influence of sulfur content in synthetic FeMn and SiMn from 0 to 1.00 wt pct on interfacial properties between these ferroalloys and slags. The effect of experimental parameters such ...
