Minerals | Free Full-Text | On Limits to Flotation Cell Size

Mechanical cells have seen an exponential increase in size over the past 60 years. However, a possible size limitation due to carrying capacity constraints has been raised. Taking a Cu porphyry case, a cell sizing exercise is used to show that possible size limitation due to carrying capacity can be tested using available techniques. A range of …

A novel scale-up approach for mechanical flotation cells

Gorain et al. (1997a,b) and Alexander et al. (2000) suggested the use of the bubble surface area flux as the scale-up criterion by considering a linear relationship with the flotation rate. This approach was tested for cells over 50 L, where they believe the hydrodynamic effect (turbulence) to be less significant.

Flotation: Recent innovations in an interesting and effective

1. Introduction. The importance of flotation, as a separation process, to the economy of the whole industrial world is considered to be enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and mechanical …

The future of flotation

Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes. First, coarser particles tend not to have as ...

SELECTION OF MECHANICAL FLOTATION EQUIPMENT

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

What Are Column Flotation Cells?

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.
