The StackCell, which is much smaller than a traditional flotation cell, can shrink the size of a flotation plant by 50%. The knock-on effect is that it also requires less concrete (smaller carbon footprint), less piping to connect the units, and fewer electrical connections and cable trays and pipe racks, thus reducing CAPEX and engineering ...

Challenges in flotation scale-up: The impact of flotation …

Two effects were found that partially explain the scale-up factor in the pulp zone, such as the pulp mixing regime (4–16%) depending on the cells number, and the solids segregation (2–7%) that decreases the residence time of larger particles.

Coal Flotation

Flotation tests were carried out in a 1.5 L lab flotation cell, at 150 g solids/L pulp density. Both flocculants were found to strongly depress coal flotation: the higher the flocculant dosage, the smaller the yield of the concentrate, higher its ash content, and lower ash content in the flotation tailings.

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.

An Overview of Optimizing Strategies for Flotation Banks

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being …

1. Introduction. One of the major challenges faced by the resources industry is the poor separation of fine gangue particles from value particles in froth flotation (Wills and Finch Citation 2016).In a flotation cell, normally the value particles are rendered hydrophobic and then attach to air bubbles and rise to the top of the flotation cell as …

Review Scale-up in froth flotation: A state-of-the-art review

The throughput treated at industrial processing plants has increased in the recent decades because of lower grades and higher mining capacities [15].Instead of the amount of cells and banks in the processing plant being increased, flotation equipment has become larger in order to process more mineral [16].Tank volume has increased a …

A review of froth flotation control

Re-circulating material through a flotation plant results in decreased residence time of material per flotation cell, but does allow for the valuable material to spend more time in the flotation plant as a whole; and, subsequently, increases the overall recovery (Wills and Napier-Munn, 2006).
