The relative density of pyrite is 5.0, that of shale is 2.4 and that of bituminous coal is approximately 1.2. The differences in these relative densities form the operating principle of the majority of today's coal preparation equipment.
Relative density. Relative density or specific gravity of the coal depends on the rank of the coal and degree of mineral impurity. Knowledge of the density of each coal play is necessary to determine the properties of composites and blends. The density of the coal seam is necessary for conversion of resources into reserves.
Anthracite is similar in appearance to the mineraloid jet and is sometimes used as a jet imitation.. Anthracite differs from ordinary bituminous coal by its greater hardness (2.75–3 on the Mohs scale), its higher relative density of 1.3–1.4, and luster, which is often semi-metallic with a mildly brown reflection. It contains a high percentage of fixed carbon and a low percentage of ...
Complex Permittivity of Graphite, Carbon Black and Coal Powders in the Ranges of X-band Frequencies (8.2 to 12.4 GHz) and between 1 and 10 GHz ... having an identical relative density over the measurement frequencies. We have also measured the relative complex
Apr 04, 2020· The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter. It is a mature coal and is very hard and shiny. Bituminous coal has a bulk density of 42 to 57 pounds per cubic feet, or 673 to 913 kilograms per cubic meter.
The bulk density of coal is influenced by its physical characteristics, such as relative density, shape and size distribution of the coal particles, on the coal moisture content as well as on the dimensions of the measuring container.
Relative density. Relative density or specific gravity of the coal depends on the rank of the coal and degree of mineral impurity. Knowledge of the density of each coal play is necessary to determine the properties of composites and blends. The density of the coal seam is necessary for conversion of resources into reserves.

Petrographic analysis of different density fractions revealed a direct proportionality of vitrinite content to swelling properties. The highest free-swelling indices (7.5 and 6.5) were observed for 1.2 density fraction of Coal A and Coal B, respectively.
The density fraction of interest was chosen to be the material with a relative density of less than 1.4 (occurring in the fractions F1.3 and 1.3 - 1.4), representing a "clean" product consisting mainly of liberated low density coal macerals. When comparing this material for the two cases, it
The field measurement of in situ density adapted the standard civil engineering technique described in AS 1289.5.3.2_1993 which explicitly measures the volume of the void left after removing a carefully weighed mass of coal using a graded sand of known bulk density.

Jul 27, 2020· The single float-sink test defines the relative amount of float-product and sink-reject that should result from the coal being washed in that preparation plant. The second type of float-sink analysis tests a coal sample in a succession of density baths to determine the optimal density for separation of the coal from rocks and minerals.

Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2].The bulk density of a coal consists of the matrix and the void space, with the latter being expectedly filled ...
