A neural network approach for spatial variation assessment – A nepheline syenite case study
(Journal article; Peer reviewed, 2020)The present geometallurgical study shows the application of a machine-learning methodology to the prediction of material properties from the Nabbaren nepheline syenite deposit in Norway. The approach used in this study ... -
Adsorptive retention of copper from acidic mine water at the disused sulphide mine at Lokken, central Norway - initial experiments using olivine
(Peer reviewed; Journal article, 2004)This paper investigates the chemical potential of using forsterite olivine to remove copper from acidic mine water through the actions of neutralisation and adsorption. The study was initiated by The Norwegian Directorate ... -
Comparison of single and mixed reagent systems for flotation of copper sulphides from Nussir ore
(Peer reviewed; Journal article, 2019)The present study investigates the application of thiol collectors and their mixtures on the flotation of copper-silver-gold minerals from a new copper mine located in northern Norway. The copper minerals (chalcopyrite, ... -
The effect of mechanical activation in the production of olivine surface area
(Peer reviewed; Journal article, 2016)This study investigates the effect of dry mechanical activation of olivine as a pre-treatment step prior to wet milling with respect to the production of specific surface area. Milling experiments combining the two milling ... -
Efficient extraction of copper and zinc from seafloor massive sulphide rock samples from the Loki's Castle area at the Arctic Mid-Ocean Ridge
(Journal article; Peer reviewed, 2018)Seafloor massive sulphide (SMS) deposits have been identified as important marine metal resources for the future. However, literature on the recovery/extraction of metals from SMS is currently limited, and to date, no ... -
Influence of jaw crusher parameters on the quality of primary crushed aggregates
(Journal article; Peer reviewed, 2020)A parameter study using a jaw crusher is designed to investigate the influence of feed gradation, feed rate, crusher setting and crusher speed on the crusher operation and the quality of the produced aggregates. The study ... -
Kinetics of froth flotation of naturally hydrophobic solids with different shapes
(Journal article; Peer reviewed, 2018)In this paper, kinetics of flotation of naturally hydrophobic polystyrene platelets with the same roundness, solidity, surface roughness and hydrophobicity but different basic shapes i.e. circular, square and triangular, ... -
Linking molecular structures of yeast-derived biosurfactants with their foaming, interfacial, and flotation properties
(Peer reviewed; Journal article, 2021)Yeast-derived bola amphiphiles have attracted growing attention in various industrial sectors as green reagents. However, their physico-chemical properties relevant to mineral separation by froth flotation are poorly ... -
Mechanical Activation of Olivine
(Peer reviewed; Journal article, 2006)This paper investigates how mechanical activation of olivine can increase the mineral’s surface reactivity, and illustrates how such technology can give rise to new or improved olivine products. The olivine material used ... -
Mineral characterization as a tool in the implementation of geometallurgy into industrial mineral mining
(Journal article; Peer reviewed, 2018)Industrial minerals play an important role in the Norwegian mining industry. The presented research focuses on defining marble deposit variability in order to evaluate parameters that can potentially be related to downstream ... -
Mineralogy and texture of the Storforshei iron formation, and their effect on grindability
(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. ... -
Multi-objective mixture design of cemented paste backfill using particle swarm optimisation algorithm
(Peer reviewed; Journal article, 2020)In order to achieve a successful cemented paste backfill (CPB) mixture design, multiple project requirements such as strength, flowability and cost should be met. For this achievement, the key design parameters, solid ... -
Non-HF collectorless flotation of quartz
(Journal article; Peer reviewed, 2019)Pure mineral flotation experiments have demonstrated that quartz can be floated without a collector, in solutions containing an inorganic acid (e.g. H2SO4) and sodium fluoride (NaF). Excellent quartz recoveries, similar ... -
Predicting the neutralisation of acid mine drainage in anoxic olivine drains
(Peer reviewed; Journal article, 2008)The precipitation of gypsum within anoxic limestone drains subjected to very acidic and sulphate rich acid mine drainage is a problem that can be prevented by initial neutralisation of the drainage using magnesium-rich ... -
