Flotation cell for iron selection

May 01, 2020 The majority of iron ore flotation research, particularly with respect to chemical conditions such as reagent selection, has been carried out using mechanical flotation cells (Yuhua and Jianwei, 2005; Vieira and Peres, 2007; Ma et al., 2011)

    Flotation Cell - an overview | ScienceDirect Topics

    Improved metallurgical performance of column cells in iron ore flotation is reported and attributed to froth washing, which reduces the loss of fine iron minerals entrained into the froth phase (Dobby, 2002). The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates

    Flotation Cells in Iron Ore Processing - Froth Flotation

    To answer your question I think it’s best to consider the anatomy of forced air vs. induced air (e.g. WEMCO) flotation cells. The induced air flotation cell has the rotor position at the top of the cell as it needs to be close to the surface to pull in air; hence the majority of the mixing energy is dissipated in the top of the cell

The selection of the size, number and type of flotation cells for a particular duty depends on two important factors. These are the required flotation residence time and the physical constraints of how much concentrate can be recovered for a given froth surface area and

    A run-away is a frightening experience for a novice flotation operator. Froth begins to flow from the surface of the cells at such a rate that launder water sprays cannot break down the froth and it then begins to overflow the launder depositing on the sump floor. Even by dropping the cell level, the froth continues to flow and cannot be stopped
