1. 1. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

   University essay from Lunds universitet/Kemiska institutionen

   Author : Niklas Gunnarsson; [2019]
   Keywords : Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

   Abstract : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. READ MORE

3. 2. Rare-Earth Elements in the Swedish Alum Shale Formation: A Study of Apatites in Fetsjön, Västerbotten

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Abstract : The Caledonian alum shales of Sweden host a vast number of economically interesting metals. In Fetsjön, Västerbotten, the shales contain significant amounts of rare-earth elements, vanadium, molybdenum and uranium. READ MORE

4. 3. Primary Study of the Phase Relationship in the MgO-"V2O3" System at 1873 K and pO2=10-11 atm

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Line Larby; Annie Lundberg; [2018]
   Keywords : ;

   Abstract : Vanadium can be found in some iron ores as an impurity. Since vanadium is a valuable alloy element there lies an interest in development of a stable and economic way for extraction of it. For this, knowledge about the thermodynamics behind the V-O system combined with other elements, like Mg, is indispensable. READ MORE

5. 4. The effect of Al2O3, CaO and SiO2 on the phase relations in vanadium containing slags

   University essay from KTH/Materialvetenskap

   Author : Martin Berg; [2015]
   Keywords : ;

   Abstract : Today, the main raw material for vanadium production is vanadium containing steelmaking slags. The yield of the vanadium extraction process is affected by the composition of the slag, which in turn determines the phases present, the fractions of the phases and the distribution of the elements between the phases.

6. 5. Vanadium for flow batteries : a design study

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Christoffer Söderkvist; [2013]
   Keywords : Vanadium Redox Flow Battery VRFB ; Vanadium extraction; Investment economics; Mineral processing; Ash handling; Sustainable energy system;

   Abstract : As society strives to transition for sustainable energy generation is it a major challenge to optimize and develop the renewable energy generation that currently exists, both in terms of individual components and their interactions in the entire energy system. The generation from renewable sources is often irregular and not always when the demand arises. READ MORE
