DR Flotation Machine - 911 Metallurgist

2016-2-29  The Metso Minerals DR Flotation Machine is the firstmechanical open type machine to incorporate a verticalcirculation of pulp, made possible by combining a“recirculation well” with the distinctive Metso Mineralstop feed impeller. This arrangement provides positivevertical circulation of pulp similar to the action in apropeller agitator. Pulp from an intermediate zone of thecell is circulated down into the eye of the impeller, mixedwith air, and diffused out over the entire bottom of thecell, creating a uniform upward current. This principle variesfrom most other mechanical open type cells whichcirculate pulp

StackcelltM Flotation - a new For Fine coal ...

2016-3-24  During the past decade, column flotation cells have become widely accepted for the upgrading of fine coal streams. this popularity can be largely attributed to the ability of columns to remove high-ash clays from the froth product via the addition of wash water to a relatively deep froth. while there are numerous successful column installations, discussions with both end-users and engineering firms have identified certain design criteria that can make these installations challenging. the greatest of these challenges is the overall size of the cells

Influence of flotation cell hydrodynamics on the flotation ...

2017-1-1  Savassi (1998) divided the pulp in a flotation cell into two zones: (1) The “Collection” zone (near the impeller), which contains high turbulence intensity and where the majority of bubble particle attachment occurs and (2) The “Quiescent” zone (outside the impeller region), which contains very low turbulence intensity and where the interaction between bubbles and particles is very low.
