NUMERICAL MODELING OF AN OUTOKUMPU

2003-11-26  3 Outokumpu Technology Minerals Processing, Riihitontuntie 7C FIN-02200 Espoo, Finland ABSTRACT This paper reviews the detailed hydrodynamics of Outokumpu flotation cells by using CFD modeling. Scope of this work was to build an industrial tool, based on CFD, for modeling flow field and solids distribution in flotation cell without air feed.

Flotation Cell Control International Mining

2005-9-15  Flotation cells have three main control parameters. (1) reagent dosing rate (2) froth depth and (3) air addition. rate. Many other parameters may vary such as feed rate, particle. size distribution and head grade, however these are the output. of upstream processes and are not controlled in the flotation. circuit itself.

Flotation cell with eccentric rotor and stator Outokumpu

A flotation cell of the type comprising at least one froth removal edge and a rotor and stator adapted to be immersed in the liquid to be flotated, in order to direct the surface flow in the flotation cell towards its removal edge or edges, the clearance between the rotor and the stator, as seen in the rotation direction of the rotor, widens in that rotational sector or those rotational

SELECTION OF MECHANICAL FLOTATION EQUIPMENT

2021-6-24  Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry,the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,,and pumped down the
