Flotation - ScienceDirect

2016-1-1  Flotation feed is generally the ball mill cyclone overflow but in cases where some of the valuable minerals are liberated at coarse sizes and are recirculated in the cyclone underflow, these can be recovered before overgrinding by treating the cyclone underflow by flotation. A flotation cell designed to treat the coarse cyclone underflow is the Skimair ® or Flash flotation cell. This is designed to

Column flotation cell design by drift flux and axial ...

2015-12-10  In research activities, a column flotation cell is commonly used where low intensity of turbulence and/or low variance of bubble size distribution are required. Based on the theories of drift flux model and first order dispersion model, a methodology is introduced in this paper which enables the researcher to calculate the dimensions of the cell for certain desired values of operational parameters.

2009-1-1  The largest flotation cells presently used in industrial flotation operations all over the world are 100, 130, 160 m3, and more recently have reached 250-300m3 per single cell. Improvements in simplicity (low number of cells), low specific energy consumption and less space have been in most cases the reasons for using these new designs.
