Bubble Formation and Motion in Liquids—A Review
Kosior, Dominik; Wiertel-Pochopien, Agata; Kowalczuk, Przemyslaw Boguslaw; Zawala, Jan (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 ... -
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) ... -
Critical synergistic concentration of binary surfactant mixtures
Zawala, Jan; Wiertel-Pochopien, Agata; Kowalczuk, Przemyslaw (Journal article; Peer reviewed, 2020) -
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, ... -
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. ...
