Adsorptive Removal Behavior of Pb (II) and Cr (VI) Pollutants from an Aqueous Environment onto Polyaniline-Modified MIL100(Fe)
(Peer reviewed; Journal article, 2023)The present work introduces a new sorbent, so-called PANI/MIL100(Fe), for removing Pb (II) and Cr (VI) from wastewater. The successful preparation of PANI/MIL100(Fe) was verified via Fourier-transform infrared spectroscopy ... -
Advanced Simulation of Quartz Flotation Using Micro-Nanobubbles by Hybrid Serving of Historical Data (HD) and Deep Learning (DL) Methods
(Peer reviewed; Journal article, 2023)The present study investigates the optimization and advanced simulation of the flotation process of coarse particles (–425 + 106) using micro-nanobubbles (MNBs). For this purpose, flotation experiments in the presence and ... -
An Assessment of the Role of Combined Bulk Micro- and Nano-Bubbles in Quartz Flotation
(Peer reviewed; Journal article, 2022)Bulk micro-nano-bubbles (BMNBs) have been proven to be effective at improving the flotation recovery and kinetics of fine-grained minerals. However, there is currently no research reported on the correlation between the ... -
Automated Mineralogy and Diagnostic Leaching Studies on Bulk Sulfide Flotation Concentrate of a Refractory Gold Ore
(Peer reviewed; Journal article, 2023)Obtaining detailed and precise information from a classified refractory gold ore has been a long-standing challenge in mineral processing and process mineralogy. Although the concept of diagnostic leaching has been extensively ... -
Bubble Formation and Motion in Liquids—A Review
(Journal article; Peer reviewed, 2023)In flotation, a bubble acts as a carrier for attached particles. The properties of the gas–liquid interface of the bubble are one of the main factors determining the bubble motion and flotation efficiency. Monitoring of ... -
Characterisation of Mineralised Material from the Loki’s Castle Hydrothermal Vent on the Mohn’s Ridge
(Journal article; Peer reviewed, 2018)Loki’s Castle on the Arctic Mid-Ocean Ridge (AMOR) is an area of possible seafloor massive sulphide (SMS)-style mineralisation under Norwegian jurisdiction, which, due to mounting social pressure, may be a strategic future ... -
Classification of flotation frothers
(Journal article; Peer reviewed, 2018)In this paper, a scheme of flotation frothers classification is presented. The scheme first indicates the physical system in which a frother is present and four of them i.e., pure state, aqueous solution, aqueous solution/gas ... -
Concentration at the Minimum Bubble Velocity (CMV) for Various Types of Flotation Frothers
(Journal article; Peer reviewed, 2017)This paper presents the determination of a concentration at the minimum bubble velocity (CMV) for different types of frothers, such as straight and branched alkyl chain aliphatic alcohols, 1,ω-diols, poly(propylene glycol) ... -

Deep-Sea Mining–A Bibliometric Analysis of Research Focus, Publishing Structures, International and Inter-Institutional Cooperation
(Journal article; Peer reviewed, 2022)Deep-sea mining is a multidimensional concept that requires interdisciplinary research and development to close the current knowledge gaps. This study conducts a bibliometric analysis of the research focus, publishing ... -
Economic block model development for mining seafloor massive sulfides
(Journal article; Peer reviewed, 2018)To support open-pit studies related to seafloor massive sulfides mining projects, an economic block-model is required. A modular framework is proposed to produce economic block models accommodating various levels of data. ... -
An Evaluation on the Impact of Ore Fragmented by Blasting on Mining Performance
(Peer reviewed; Journal article, 2022)In open-pit mines, the blast operation should be effectively optimized, leading to minimization of production costs through the application of specific technical specifications. However, there is inadequate information in ... -

Geometallurgical Approach to the Element-to-Mineral Conversion for the Nabbaren Nepheline Syenite Deposit
(Journal article; Peer reviewed, 2018)Nabbaren nepheline syenite, a silica-deficient intrusive rock with low Fe content, was the industrial mineral deposit study case in this study. The quality of industrial mineral products are generally based on their bulk ... -
Geometallurgical Flowsheet as a Tool for Designing and Communicating Geometallurgical Programs
(Journal article; Peer reviewed, 2018)This paper introduces the concept of using a geometallurgical flowsheet as a tool to design, visualize and communicate a geometallurgical program. The development of the concept is carried out using a case study of an ... -
The graphite occurrences of Northern Norway, a review of geology, geophysics, and resources
(Peer reviewed; Journal article, 2020)There are three provinces in Northern Norway in which occurrences of graphite are abundant; the Island of Senja, the Vesterålen archipelago, and the Holandsfjorden area. From these provinces, we report graphite resources ... -
Hybrid Serving of DOE and RNN-Based Methods to Optimize and Simulate a Copper Flotation Circuit
