Coal assay - Wikipedia

2019-2-28  The density of the coal seam is necessary for conversion of resources into reserves. Relative density is normally determined by the loss of a sample's weight in water. This is best achieved using finely ground coal, as bulk samples are quite porous. To determine in-place coal tonnages however, it is important to preserve the void space when ...

relative density of coal - ellul.nl

Relative coal density is measured as specific gravity. Specific gravity is the ratio of the mass of an object (solid or liquid) to the mass of an equal volume of water at 4°C. For reference, the specific gravity of water is 1. Materials with specific gravities of less than 1 float

Relative density - Wikipedia

2019-2-28  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 usually means relative density with respect to water. The term "relative density" is often preferred in scientific usage.
