En petrologisk og geokjemisk studie av pegmatittiske og aplittiske intrusjoner i marmor på Akselberg, Brønnøy kommune, Nordland
Tøgersen, Marte Kristine (Master thesis, 2011)The field area is situated in the marble deposit in Akselberg, Velfjorden in the southern part of the Helgeland Nappe Complex, and is mined by Brønnøy Kalk AS. The marble is intruded by several granitic dikes. Fieldwork ... -
Mineralogical and textural characterization for increased iron oxide recovery. Exemplified on the Storforshei iron formation
Tøgersen, Marte Kristine (Doctoral theses at NTNU;2019:309, Doctoral thesis, 2019)Process mineralogy is increasingly becoming an important part of quality control in mining operations, and chemical assays are not sufficient for predicting metallurgical performance of complex ore deposits. Knowledge of ... -
Mineralogy and texture of the Storforshei iron formation, and their effect on grindability
Tøgersen, Marte Kristine; Kleiv, Rolf Arne; Ellefmo, Steinar Løve; Aasly, Kurt (Journal article; Peer reviewed, 2018)Investigating how ore mineralogy and texture affect the recovery from the processing plant is important for any mining operation. The results will assist in production planning and optimising the utilisation of a deposit. ...
