Gold Gravity Concentration - Mineral Processing Metallurgy

Oct 30, 2016  Gold Gravity Concentration. 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 ...

Concentration determination by means of density ...

The difference ∆ of 1.0 %w/w corresponds to a density change of 0.0071 g/cm³, thus the accuracy of the NaCl solution is: (1.0 x 0.000005)/0.00710 = 0.007 %w/w. This is the average accuracy for the overall range as defined above, and only true assuming the relation of density to concentration is linear.

Relative density - Wikipedia

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" is often preferred in ...
