Common & Basic Formulas for Mineral Processing Calculations
Pulp densities indicate by means of a tabulationthe 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 to…

Iron ore beneficiation: an overview
The beneficiation plant is designed to process less than 10 mm of low-grade iron ore fines. Low-grade fines fed to the plant are scrubbed and then classified into two size fractions, that is, +0.5 and −0.5 mm utilizing vibratory screens.

Formula (5) is used in making tabulations for mill use. As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity.

Beneficiation Plant Yield Calculation Iron Ore
Chemical beneficiation of chromite ore to improve the chromium-to-iron. Conventional methods of beneficiation such as gravity concentration, magnetic separation, and flotation cannot effectively increase the Cr/Fe ratio in chromite ore unless the Fe occurs in the gangue materials ( Murthy et al., 2011, Nafziger, 1982) since the Fe content mainly depends on the spinel composition.
