(Journal article; Peer reviewed, 2019)he Norwegian mining industry is currently showing increasing interest in the production of metals. Recent research has demonstrated promising results identifying the high potential of the Nussir deposit for the production ... -
An Invitation on Characterization of H<inf>2</inf>-Reduced Bauxite Residue and Recovering Iron through Wet Magnetic Separation Processes
(Peer reviewed; Journal article, 2023)Recovering iron from the bauxite residue (BR) is one of the long-standing challenges in the mining industry. However, there is a substantial lack of information in the literature regarding sample properties and iron ... -
Mining Ground Deformation Estimation Based on Pre-Processed InSAR Open Data—A Norwegian Case Study
(Journal article; Peer reviewed, 2023)Sublevel caving mining causes surface deformation in three distinct zones parallel to the extracted deposit. Most of the published research is focused on the extent of the caved and fracture zones. The extent of the largest, ... -
Prospectivity Mapping of Mineral Deposits in Northern Norway Using Radial Basis Function Neural Networks
(Journal article; Peer reviewed, 2019)In this paper, the radial basis function neural network (RBFNN) is used to generate a prospectivity map for undiscovered copper-rich (Cu) deposits in the Finnmark region, northern Norway. To generate the input data for ... -
Quartz Fine Particle Processing: Hydrophobic Aggregation by Shear Flocculation
(Peer reviewed; Journal article, 2023)This study investigates the hydrophobic aggregation of fine quartz particles through shear flocculation induced by dodecylamine in aqueous solutions. The effect of stirring speed, collector concentration, flocculation time, ... -
Recent Advancements in Metallurgical Processing of Marine Minerals
(Peer reviewed; Journal article, 2021)Polymetallic manganese nodules (PMN), cobalt-rich manganese crusts (CRC) and seafloor massive sulfides (SMS) have been identified as important resources of economically valuable metals and critical raw materials. The ... -
Recent developments in generation, detection and application of nanobubbles in flotation
(Peer reviewed; Journal article, 2022)This paper reviews recent developments in the fundamental understating of ultrafine (nano) bubbles (NBs) and presents technological advances and reagent types used for their generation in flotation. The generation of NBs ... -
Residence Time Distribution Measurements and Modeling in an Industrial-Scale Siemens Flotation Cell
(Peer reviewed; Journal article, 2023)This short communication presents residence time distribution (RTD) measurements and modeling in a 16 m3 Siemens flotation cell, as the first RTD characterization in an industrial-scale pneumatic cell. The Siemens cell was ... -
Rock Classification Using Multivariate Analysis of Measurement While Drilling Data: Towards a Better Sampling Strategy
(Journal article; Peer reviewed, 2018)Measurement while drilling (MWD) data are gathered during drilling operations and can provide information about the strength of the rock penetrated by the boreholes. In this paper MWD data from a marble open-pit operation ... -
Simultaneous leaching of seafloor massive sulfides and polymetallic nodules
(Journal article; Peer reviewed, 2019)Simultaneous leaching of seafloor massive sulfides (SMS) from Loki’s Castle on the Arctic Mid-Ocean Ridge (AMOR) and polymetallic nodules (PN) from Clarion Clipperton Zone (CCZ) of the Central Pacific Ocean was studied. ...
