Treatment of liquid effluents is a serious challenge owing to the high stability and colloidal nature of the particles. In many applications, microbubbles (< 150 µm) are employed for separation purposes due to their buoyancy and increased surface area to volume ratio. This property has been exploited in the water treatment industry for separation in a process …

Optimizing Flotation Cells. H ow a flotation cell works . Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry.
In general, the industrial flowsheets for the beneficiation of itabirite iron ores from the Quadrilátero Ferrífero (Minas Gerais state) in Brazil involves grinding, desliming, magnetic separation and cationic reverse flotation using both mechanical and columns flotation cells. At Brazilian plants, it is estimated that Fe losses generated at the slimes …
A simple empirical dimensionless model to calculate the mineral gangue recovered per size class (R G,i) by entrainment, in terms of the water recovery (R W), in an industrial flotation cell is presented.For modeling purposes, a dimensionless entrainment factor EF i, corresponding to the ratio (R G,i /R W), was defined for each particle size …

1.. IntroductionFlotation is an important process in the minerals industry and most flotation is carried out using mechanically agitated cells ranging in volume up to 300 m 3.Separation of the particles of valuable minerals from the ore is achieved when particles of the valuable minerals preferentially attach to air bubbles and are floated to the surface …
Flotation is a process of separating particulate materials of different surface properties in a hydrodynamic environment, and is used extensively for separating different minerals from each other in the mining industry. In this process, air bubbles are introduced at the bottom of a particulate suspension (pulp), so that bubbles coated with hydrophobic particles rise …

The complex mechanism of the flotation cell is less understood due to the rotor-stator arrangement and the physio-chemical interaction inside the cell. CFD simulations provide an efficient tool to study the complex unsteady multiphase flow prevailing in the flotation cell and has the potential to identify design and process improvement.
Separating minerals in a froth flotation cell has a particularly corrosive effect on a slowly rotating rake and its components. Mixtures of slurry, surfactant, water, air and froth can quickly lead to failed seals and bearings. Which, of course, means costly unplanned downtime and lost productivity.
