  • Estimating tons of coal on a property , Kentucky ...

    Because specific gravity is measured relative to water, specific gravity, the weight of water, and the area of the seam can be used to determine tonnage. According to the U.S. Geological Survey (Wood and others, 1983), the average specific gravity of unbroken (solid) bituminous coal is 1.32. Given that: Specific gravity of bituminous coal = 1 ...

    Density of Coal may vary, depends on the type (structure) and form. Below are some density of coal : - Coal, Anthracite, solid 1.506 gr/ml - Coal, Anthracite, broken 1.105 gr/ml - Coal, Bituminous ...

  • Bituminous Coal Characteristics and Applications

    Bituminous coal contains the mineral pyrite, which serves as a host for impurities such as arsenic and mercury. Burning the coal releases trace mineral impurities into the air as pollution. During combustion, approximately 95 percent of bituminous coal's sulfur content

  • What Is the Bulk Density of Coal? Reference

    The bulk density of coal depends on the specific type of coal. It can range from 40 to 58 pounds per cubic feet, or 641 to 929 kilograms per cubic meter. 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.

  • Bituminous Coal - an overview ScienceDirect Topics

    Very clean bituminous coal has a specific gravity of approximately 1.3, very pure anthracite 1.6, shales usually have values around 2.4 and iron pyrites 5. The behavior of raw coal in a wet washer can be predicted from laboratory simulation tests known as float and sink test and washability test.

  • Specific Gravity Of General Materials Table

    The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

  • 煤化程度 的翻译结果--cnki翻译助手

    Relationship between the chemical compositions of coal and the true specific gravity of dry, ash-free coal has been studied. It has been found that true specific gravity of coal varies regularly with some parameters characterizing the degree of coalification, such as the contents of carbon, oxygen, volatile matter and aromaticity.

  • Bituminous coal - Wikipedia

    2020-6-2  Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt.It is of higher quality than lignite coal but of poorer quality than anthracite.Formation is usually the result of high pressure being exerted on lignite. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the ...
