Efficient air dispersion cuts down on frother consumption. Reduced mechanism erosion lowers your maintenance costs. Whether incorporated into our original 1+1 flotation machine design or our newergeneration SmartCell flotation cell, selfaspirating inducedair flotation technology combines ease of operation with improved metallurgical performance.

Froth flotation efficiency is determined by a series of probabilities: those of particle–bubble contact, particle–bubble attachment, transport between the pulp and the froth, and froth collection into the product launder. In a conventional mechanically agitated cell, the void fraction is low (5–10%) and the bubble size is large (2–3 mm), which results in a low interfacial area with a

The strongly hydrophobic and optimisedsized particles are likely to float first in a bank of flotation cells. Sluggish flowing particles float in diminishing order, and so forth, giving rise to total recovery of about . A minimum of four cells is required for coal flotation with a residence time of 5 minutes (Euston et al., 2012).

Flotation is a complex process that is affected by a multitude of factors. These factors may be inherent in the circuit design, or in how the flotation plant is operated. The FloatStar suite of control modules utilises advanced process control to overcome designrelated limitations and maximise circuit performance during operation. As far as possible, Mintek''s control modules are designed to

Flotation Laboratory Flotation Cell The technological results of the flotation process depend on furnish, chemicals used and the process itself. Process variables are the air content, aeration intensity and frequency, stock consistency, loss rate and dwell time.

flotation cell will be used to estimate recovery by the entrainment mechanism. Thus known quantities (or no) water should be used to wash concentrate into the tray. Samples to be tested can be collected directly from an operating flotation circuit, referred to as ''hot samples'', or prepared in the laboratory – grinding to produce the appropriate particle size or adding reagent to achieve

Remixing of the air coming from downstream stages of the process helps the upstream stages and improves the overall cell efficiency. Adjustable and selective losses of fiber depend on the application and technical requirements – inks, or inks and fillers. The use of lowpressure injectors in the MAC flotation cell could save about 25–30% of the energy used in conventional flotation systems

We have equipped our forcedair flotation tank cells with a uniquely designed, highefficiency radial launder system that accelerates froth removal as it reaches the surface. Bubbleparticle aggregates travel vertically through the froth lattice. The highefficiency radial launder is shaped to receive the froth uniformly from the cell surface, as well as from the typically heavyloaded area
