  • Common Basic Formulas for Mineral Processing Calculations

    Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly because for each unit process and operation in milling the optimum pulp density must be established and maintained and indirectly because certain important tonnage calculations are based on pulp density.
