Pulp Formulas & Metallurgical Formulas

Definitions. "Pulp," in flotation terminology, is a freely-flowing mixture of powdered ore and water. "Pulp density," when the phrase is applied properly, indicates the specific gravity of the pulp. "Percentage of solids" means the ratio, expressed as a percentage, of the weight of the solids in a pulp to the total weight of pulp.
