  The effect of grinding conditions on the flotation of a sulphide copper ore

  2003111 · The grinding conditions affect significantly the subsequent flotation stage of this sulphide copper ore. The presence of iron ions in the slurry is deleterious to the flotation of copper minerals and may be avoided by the utilisation of lined mills and non-ferrous or corrosion resistant grinding media, such as stainless steel or pebbles.

  The Importance of pH in Flotation - 911 Metallurgist

  2015810 · 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 …
