less documented for UG2 ore flotation This study investigated the effect of the interaction of the process variables in UG2 ore flotation The investigations were carried out in a laboratory column flotation cell for a UG2 ore with a feed size of 60 passing 75 microns The column flotation cell was useful for studying deep froths at steady state

Gas dispersion results show that air flow rates air flow numbers and air flow velocities vary significantly from cell to cell but are within the range typically found in industrial flotation cells

Nov 01 2003 · The gas flow rate was decreased from 53 Lmin J g ∗ 09 cms to 30 Lmin J g ∗ 05 cms and then increased to 74 Lmin J g ∗ 13 cms Fluctuations in the gas flow rate entering the cell also produce adjustments in level

Oct 01 2005 · The air flow rate in the cell was set at 38 dm 3 STPmin Jg 07 cms and the impeller speed was set at 1050 rpm The solid concentration was varied over the range of 0–30 kgkg using two frothers DF250 and DF1012 at concentrations of 15 ppm and 10 ppm respectively

Jan 01 2012 · Based on direct measurements of the superficial gas rate and bubble size distribution measurements using the UCT bubble size analyser Randall et al 1989 Yianatos et al 2001 reported S B estimates in 425 m 3 industrial flotation cells of S B 72 ± 185 m 2 sm 2

The column flotation group at the University of Cape Town for their input into this project pulp was most affected by the pulp density and the air rate had the biggest RESIDENCE TIME DISTRiBUTION STUDIES 33 IN COLUMN FLOTATION CELLS
