  • Some gas dispersion characteristics of mechanical

    May 01, 2006The paper focuses on forced air mechanical machines: at Raglan, nominal 28m 3 Outokumpu OK28 Ubottom cells; at LDI, 130m 3 Outokumpu OK130 tank cells; and at Impala, 50m 3 Bateman 50 and 30m 3 RCS 30 tank cells. Common gas dispersion features are identified, for example the dependence of bubble size on gas rate.

  • TECHNICAL NOTES 9 FLOTATION

    Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.
