The Importance of pH in Flotation

This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS PAPER or a pH METER is used. This is a very important measurement for the flotation operator.
