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.

Sintering Characteristics of Indian Chrome Ore Fines
· Chrome ore concentrate consists of high-temperature melting oxides such as Cr2O3 MgO and Al2O3. The presence of these refractory constituents makes the ore a very high melting mineral. Hence it is difficult to produce sinter from chrome ore by a pyrometallurgical route. Currently chrome ore is ground to below 75 μm pelletized heat hardened through carbothermic reaction at 1300 °C to
