Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.

At the Huasco Pellet Plant of Compaa de Aceros del Pacfico, Chile, the production of iron concentrate suitable for pellet feed from a lowgrade iron ore was technically evaluated. In this study, three treating schemes including comminution, magnetic concentration and flotation in pneumatic cells were tested. The best results were obtained at the laboratory scale by flotation technique using ...
With the aim of producing a concentrate with silica content lower than per cent SiO2, laboratory experiments were conducted using a sample of the final concentrate from the Samarco iron ore flotation plant (mechanical cells circuit). The sample contained per cent SiO2. This sample was split in two size ranges: >105 m and <105 m. The <105 m fraction, representing per cent of the ...
cleaner flotation cells, which produce successively higher grade concentrates. This flotation slurry, also referred to as pulp, contains from 25 to 40 percent solids. After the series of concentration steps, the final copper concentrate is sent to thickeners and pressure filters where the moisture content is reduced
All flotation tests were conducted at room temperature with a 1000 ml Denver laboratory flotation machine. Pulp density was adjusted to about 30% solid by weight. The pulp was conditioned in the flotation cell for 10 minutes for each test before air was introduced. Flotation (concentrate collecting) time was set at 4 minutes for each test.

Imhoflot GCells are used to produce the flotation concentrate. The reason for this is that the patented GCell is able to produce a higher grade flotation concentrate than conventional mechanical flotation cells resulting in a small concentrate mass and so reduced treatment costs (see under Imhoflot flotation for more information)
Processing such flotation concentrate by ... The challenges in processing nickel laterite ores using flotation ... and recovery of such particles is low in the conventional flotation cells.
The ore was reduced a size of mm after two crushing stages. It is packaged with homogeneity for use in grinding and flotation experiments. This ore sample was milled at a mill size Ø180x362 mm with an internal volume of 9 L. It was ground (d 80=75 μm) and fed to the flotation cell (Fig. 2). Figure 2. The flotation device used in the ...

The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation. Furthermore, flotation cells are sensitive to solid overloading.
· If the froth machine contains much ore slurry, it will bring a series of adverse effects on flotation cells mineral processing. The main influences are as follows 1 Easy to be mixed in the product, so that the concentrate grade is reduced. 2 Easy to cover the coarse grain surface, affecting the flotation of coarse particles. 3 Adsorption of a large number of agents, increase drug ...

RFCUpscaling proposes the Reflux Flotation Cell (RFC) technology for mineral processing companies, with ROI in 3 – 4 years. Within the project, it is planned to commercialise the technology as a new product of FL for copper and iron ore. The RFC requires 30 % less capex and 20 % less opex compared to the existing flotation technologies.
