Flotation Cells in Iron Ore Processing Froth Flotation

Flotation Cells in Iron Ore Processing (5 replies) The mixing and air dispersion actions on an induced air cell cannot be decoupled so this is more difficult. Also it is quiet difficult for a rotor located at the top to get sanded material in the bottom of the cell moving.

    Introduction to Mineral Processing Chevron Phillips Chemical

    Introduction to Mineral Processing. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer. Sulfide and non-sulfide minerals as well as native metals are recovered by froth flotation.

    Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

    1 Froth Flotation Fundamental Principles

    For example, if 20% of the water entering a flotation cell is carried into the froth, then up to 20% of the fine particles entering the cell will be entrained. The entrainment of coarser particles will be less than 20%, due to their greater ability to drain from the froth.

    The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates. Several companies, including Samarco Mineração S.A., Companhia Vale do Rio Doce (CRVD), Companhia Siderúrgica Nacional (CSN), and Minerações Brasileiras (MBR), are using column cells at present ( Peres et al., 2007 ).
