• Classification of flotation frothers 

      Drzymala, Jan; Kowalczuk, Przemyslaw (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 ...
    • Galvanic Leaching of Seafloor Massive Sulphides Using MnO2 in H2SO4-NaCl Media 

      Kowalczuk, Przemyslaw; Dan, Oliric Manaig; Drivenes, Kristian; Snook, Ben; Aasly, Kurt; Kleiv, Rolf Arne (Journal article; Peer reviewed, 2018)
      This paper reports the leaching of seafloor massive sulphides (SMS) from the Loki’s Castle area at the Arctic Mid-Ocean Ridge in sulphuric acid with manganese dioxide and sodium chloride. The results presented are of various ...
    • Heterocoagulation of shale particles and bubbles in the presence of ionic surfactants 

      Polowczyk, Izabela; Kruszelnicki, Mateusz; Kowalczuk, Przemyslaw (Journal article; Peer reviewed, 2018)
      Adsorption of surfactants is one of the important feature governing interactions between particulate matters. When interactions occur between two particulates, which differ from each other, heterocoagulation takes place. ...
    • Kinetics of froth flotation of naturally hydrophobic solids with different shapes 

      Szczerkowska, Sabina; Wiertel-Pochopien, Agata; Zawala, Jan; Larsen, Erik; Kowalczuk, Przemyslaw (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, ...
    • Non-HF collectorless flotation of quartz 

      Larsen, Erik; Kowalczuk, Przemyslaw; Kleiv, Rolf Arne (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 ...
    • Oil agglomeration of metal-bearing shale in the presence of mixed cationic-anionic surfactants 

      Polowczyk, Izabela; Kruszelnicki, Mateusz; Kowalczuk, Przemyslaw (Journal article; Peer reviewed, 2018)
      This paper reports oil agglomeration of fine metal-bearing shale particles in the presence of cationic (dodecylamine hydrochloride) and anionic (sodium dodecyl sulfate) surfactants and their mixture. The experimental results ...
    • Simultaneous leaching of seafloor massive sulfides and polymetallic nodules 

      Kowalczuk, Przemyslaw; Bouzahzah, Hassan; Kleiv, Rolf Arne; Aasly, Kurt (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. ...
