gravity concentration in measurable terms

Gold Gravity Concentration - Mineral Processing Metallurgy

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal is ...

Gravity Concentration Gekko

Gravity concentration separates minerals based on differences in specific gravity. Specific gravity is the weight of the same volume of material compared to water, where the specific gravity of water equals 1. The specific gravity of gold is 19.3, so it is 19.3 times as dense as water.

The Mathematics of Gravity Concentration

It is still possible, however, to present known facts from a different point of view, and, with this in mind, the writer has undertaken to express basic principles of gravity concentration in terms of simple mathematics and mechanics; the conclusions thus reached will be found to correspond, in general, with those obtained by experimental methods.

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.
