The Life Cycle of Water Used in Flotation: a Review
In order to enhance the coal flotation in a high pulp density slurry, new equipment such as a flash flotation machine, hydraulic machine, and series flotation column were developed and applied in high pulp density flotation; e.g., Xie et al. combined a jet flotation column (JFC) and a cyclonic micro-bubble flotation column (FCMC) into …
Basic Study of Flotation Dynamics | SpringerLink
The optimum size range of froth flotation varies with the flotation process parameters and flotation machine types. Too coarse or fine sizes are not suitable for flotation, that is to say, a suitable flotation size is subject to upper and lower limits. The optimum size range for froth flotation has the lower limit of about 3–7 μm based on a ...
