  • 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.

  • Study on Size and Density Distribution in Fine Coal Flotation

    the coarse coal has good selectivity, but the flotation rate is slow. When the particle size is too big, the bubbles can not carry over and hence it is lost in the tailings. Conversely, for fine coal particles the selectivity is poor and flotation rate is high. By comparison, it can be predicted that medium size coal particles should have good

  • A Review of CFD Modelling of Flotation Cells

    A flotation cell could be generally divided into two distinct zones, as shown figure 1 [5], the pulp zone and the froth zone. The overall performance of the flotation system relies on the collective result of these two zones. During the flotation process, air is injected into suspension of ore and water where a small quantity of flotation
