  • A study of bubble size evolution in Jameson flotation

    The Sauter mean diameter (d 32) of bubbles was characterized for a gas–liquid system in a laboratory Jameson-type flotation cell with focus on the size variation in the uprising path of the bubbles in the riser of the flotation cell.Methyl isobutyl carbinol (MIBC) was used as frother for bubble stability. The effect of MIBC concentration, sampling height in the riser, gas flow rate (J g) and ...

    For dewatering of flotation products, filtration is the most commonly used technology which uses various driving forces, such as vacuum, pressure and centrifugal forces, to separate liquid from solids (Hogg, 2000, Tao et al., 2000a, Tao et al., 2000b, Concha, 2014).In many plants, thickening is also applied prior to filtration to reduce the amount of water to be removed by filtration, which ...

    2020-6-13  The primary mechanism for flocculation in a bubble column device is orthokinesis. Thus, the rate of flocculation is proportional to the velocity gradient and concentration of flocculable particles. The velocity gradient in a bubble column may be estimated using: G = √U2p1g/µ where G is the velocity gradient, Ug is the superficial gas velocity, p1, µ and g are the liquid density, viscosity ...
