Ore dressing chemical method addition of flux

Mar 20, 2016 or Addition of a Chemical Substance. When no other method is available an approximation of the tonnage in a pulp stream or in a batch of pulp can be quickly obtained by one of these methods. In the dilution method water is added to a stream of pulp at a known rate, or to a batch of pulp in known quantity, and the specific gravity of the pulp
