Additionally, the use of high frother concentration can result in persistent and too stable froth formation, leading to overflow in the flotation cells, pumping problems and handling difficulties in the flotation concentrator (Bournival et al., 2017a, Wei et al., 2014). As a consequence of this significant influence of frothers on the overall ...

An Overview of Optimizing Strategies for Flotation Banks
Although a bank is the simplest interconnection of cells in a circuit, i.e., the tails of one cell is the feed to the next cell down the bank, how to operate each flotation cell in a way that the whole bank performance is optimized remains a challenge.Significant efforts have been made towards understanding the effect of operating variables on the flotation performance of …

The design of cell-based flotation circuits is often completed in two distinct phases, namely circuit structure identification and equipment sizing selection. While recent literature studies have begun to address the implications of stochastic analysis, industrial practice in flotation circuit design still strongly favors the use of deterministic metallurgical modeling …
1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
Review on advances in mineral processing technologies …
Mechanical flotation cells utilise an impellor to agitate the slurry and produce turbulent regions for bubble particle attachment, whereas in pneumatic flotation cells pulp and air are introduced together into the cell through a nozzle, also termed a downcomer, that promotes bubble-particle contact (Gupta and Yan, 2016).

Fine and ultrafine flotation with the Concorde Cell TM
The Concorde Cell is a high-intensity pneumatic flotation cell dedicated to fines and ultrafines. Its development by Professor Graeme Jameson and later on by was driven by two considerations: a reduction in bubble size and an increase in the shear rate and energy dissipation rate increases the particle–bubble collision and attachment efficiencies of fine …

Flotation circuits use multiple flotation cells in series to recover the maximum amount of desired minerals. Circuits consist of a set of cells called rougher, cleaner, and scavenger, as illustrated in Figure 5. Rougher flotation cells are usually mechanical type and appear first in the circuit, to increase the recovery of the valuable minerals.

They found that the ore floatability parameter remained constant at a constant chemistry for the industrial flotation cells larger than 60 L (Gorain, 1997a, Gorain, 2006). In their studies, the particle size was rather fine, with a P 80 of 20–25 µm. This model has not been validated for flotation cells smaller than 60 L.
