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 To have a positive control over flotation, it is necessary to be
