A Review of CFD Modelling of Flotation Cells

2014-12-18  Froth flotation is a complex physico-chemical process which is extensively used in mineral industry to separate hydrophobic minerals (valuable minerals) from hydrophilic ones (gangue). Recently, the usage of flotation process has been extended to a wide range of applications such as de-inking of recycled paper, water treatment and electrolyte cleaning (oil separation) [2, 13, 20]. Principles of flotation cell

CFD modelling of bubble–particle attachments in flotation ...

2006-5-1  In CFD modelling, the flotation cell is discretized into individual finite volumes where local values of flow properties are calculated. The flotation effect is studied as three sub-processes including collision, attachment and detachment. In the present work, these sub-processes are modelled in a laboratory flotation cell.

1 Froth Flotation – Fundamental Principles

2009-8-27  Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1. It is therefore important to take all of these factors into account in froth flotation operations. Changes in the settings of one factor (such as feed rate) will automatically cause or demand changes in other parts of the system (such as flotation rate,

2008-2-1  The collection zone residence time distribution (RTD) of mechanical self-aerated flotation cells was characterized for liquid and solid per size class (−45 µm, +45–150 µm and +150 µm). It was found that a single large industrial cell with a volume of 130 to 250 m3, now used in plant operations, can be well represented by an LTST (large and small tank-in-series) model plus dead time ...

Engineering and Science in Flotation Cell Design

In the 1990s round flotation tanks were introduced as a result of the lower fabrication costs for larger cells. It was soon observed that round tanks held a number of further advantages over the traditional rectangular cells, such as better hydrodynamics, lower costs and reduced footprint per unit volume.In the last twenty years flotation cell sizes have increased almost exponentially and ...

What Are Column Flotation Cells?

2019-2-6  The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.
