Influence of hydrodynamic variables on scaling up of

Outotec GTK LabCell™ flotation cell, a mechanical laboratory-scale batch flotation machine, has been recently introduced to the market and is widely used for industrial pre-feasibility studies. This flotation machine is comparable to other Outotec industrial-scale flotation equipment in terms of the design of its rotors and impellers, An Induced Gas Flotation (IGF) machine is a water treatment device that utilizes the flotation characteristics of air bubbles (Yiantos, 2007 ). The working principle of an IGF is that air bubbles are directly injected into the vessel and forced through a flow passage. Then, the discharged air spreads through the entire IGF vessel via a rotor.Numerical analysis on performance of induced gas flotation machine

Flotation machine design: impeller—stator interaction

Flotation machine design: impeller—stator interaction. The separate contributions of impellers and stators to suction are studied by means of interaction models. From these, suction can be predicted when interchangeable components are used in any combination, and in either direction of impeller rotation. Methods are devised by which of the growing use of CFD in flotation machine design, there are scarce reports concerning its use in the scale-up of flotation cells in li terature (Mesa and Brito-Parada, 2019).(PDF) Hydrodynamics of froth flotation and its effects on fine

Hydrodynamics of froth flotation and its effects on fine and

The half-spherical impeller system, as found in commercial flotation cells such as Bateman cells, Dorr-Oliver cells and Outokumpu cells, is becoming the most popular design in new flotation machines (Gorain et al., 2000). The stator is a stationary structure around the perimeter of the impeller.Flotation tests were carried out in a 1 L flotation machine (XFDⅣ-1 L, Jilin exploration machinery factory, Changchun, China), which is a mechanically stirred and commonly used piece of flotation equipment in mineral processing.

A Review of Flotation Physical Froth Flow Modifiers

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the Probably the most significant area of change in mechanical flotation machine design has been the dramatic increase in machine size. This is typified by the data of Fig. 8, which shows the increase in machine (cell) volume size that has occurred with a commonly used cell manufactured by Wemco.The idea behind this approach is that as machine size Flotation Machine an overview ScienceDirect Topics
