Concentration at the Minimum Bubble Velocity (CMV) for Various Types of Flotation Frothers
Kowalczuk, Przemyslaw B.; Zawala, Jan; Drzymala, Jan (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) ... -
Efficient extraction of copper and zinc from seafloor massive sulphide rock samples from the Loki's Castle area at the Arctic Mid-Ocean Ridge
Kowalczuk, Przemyslaw B.; Snook, Ben; Kleiv, Rolf Arne; Aasly, Kurt (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 ... -
Kinetic separation curves based on process rate considerations
Drzymala, Jan; Ratajczak, Tomasz; Kowalczuk, Przemyslaw B. (Journal article; Peer reviewed, 2017)There are many graphical representations of separation results involving time as a crucial parameter determining the kinetics of a process. The graphical representations of results of separation are usually in the form of ... -
Surface roughness in bubble attachment and flotation of highly hydrophobic solids in presence of frother – experiment and simulations
Kosior, Dominik; Kowalczuk, Przemyslaw B.; Zawala, Jan (Journal article; Peer reviewed, 2017)In this paper, the kinetic of the three-phase contact (TPC) formation and the flotation recovery of highly hydrophobic solids with different surface roughness were studied in pure water and aqueous solutions of n-octanol. ...
