Factors Affecting the Copper Mining Process Xinhai

Dec 22, · Pulp density is the solid content of the pulp. Usually, it refers to the mass rate of solid and liquid in the pulp. Pulp density has a great influence on the concentrate recovery rate, concentrate grade and the reagent dosage. The froth flotation is the separation between the liquid and gas surface, so the froth has a great function.
