Life Cycle Analysis of remediation and utilization of bauxite residue: Evaluation of technologies from a location perspective.
Gjedde, Philip (Master thesis, 2021)Bauxit rester eller redmud er gruvedriften rester (tailing) fra Bayer-prosessen med bauxittmalm, og med 4,6 milliarder tonn i reserver av farlige avfallsverdier er det nødvendig å inkludere det som restressurs i sirkulær ... -
Life Cycle Assessment of silicon metal by aluminothermic reduction: an industrial symbiosis approach
Pastor Vallés, Elisa (Master thesis, 2021)Silicon is a Critical Raw Material of high economic importance that also faces a great supply risk in Europe. Conventionally, silicon is produced by reducing quartz with carbon, in a process known as carbothermic reduction ... -
Life Cycle Based Climate Emissions of Charcoal Conditioning Routes for the Use in the Ferro-Alloy Production
Surup, Gerrit Ralf; Kaffash, Hamideh; Ma, Yan; Trubetskaya, Anna; Pettersen, Johan Berg; Tangstad, Merete (Peer reviewed; Journal article, 2022)Renewable reductants are intended to significantly reduce CO2 emissions from ferro-alloy production, e.g., by up to 80% in 2050 in Norway. However, charcoals provide inferior properties compared to fossil fuel-based ... -
Oxidation and Fume Formation from Liquid Silicomanganese Alloys Exposed to Atmospheres Containing Moisture
Ma, Yan; moosavi-khoonsari, Elmira; Myklebust, Håkon A Hartvedt Olsen; Tranell, Gabriella (Peer reviewed; Journal article, 2022)In industrial applications and laboratory studies, it has been shown that the use of water spray may significantly reduce the amount of fume generated from the oxidation process of liquid high carbon ferromanganese alloy. ...
