    The Importance of pH in Flotation

    Aug 10, 2015 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

    Jan 01, 2016 There are several factors of cell operation that are important in the determination of the flotation rates. If it is assumed that the collision of particles with freely moving bubbles is the dominant mechanism, and that bubble precipitation provides a favourable preliminary step to collision and adhesion, then for a given flow rate of air to a cell, an increase in impeller speed should cause more

    The linear structure of the flotation cells has a large surface area, which has reject separation and fiber loss. This flotation cell design also contributes to high sludge consistency (less water in the sludge) by ensuring smooth drainage of froth (Aksela, 2008). The elliptical shape of the flotation cells in this technology is optimal for
