    1 Froth Flotation – Fundamental Principles

    Flotation equipment include flotation machines and flotation columns Flotation columns are widely used than flotation machines in fine mineral processing At present column flotation technology is applied not only in mineral processing but also in wastewater treatment pulp deinking oil water separation and other processes.COLUMN FLOTATION ABSTRACT Industrial application of column flotation began in earnest in the early 1980’s and is now accepted as a conventional application For example most of the world’s major copper producers use column flotation as the particles Slurry was drawn out the bottom of the column and solvent overflowed the top lip.Dec 19 2013 Flotation column is widely used as the separation equipment for fine mineral due to its high selectivity However this device may be unsuitable for the coarse particle flotation and has high handling ability A two stage flotation column with dimensions of 2 000 mm 1 000 mm 4 000 mm was designed to enhance the column flotation process The energy input was modified by adjusting the.
