The Importance of pH in Flotation
In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic.

Correlation between Flotation and Rheology of Fine Particle
It is known that flotation of minerals/particles by a conventional mechanical flotation cell is typically applicable for a particle size range from 10 to 100 μm [ 32 ]. Floatable particle size range can also be varied with mineral type/density, and the maximum size can be extended to 500 μm [ 14, 33, 34 ].
