  • Coalpail - Anthracite Coal (Hard Coal)

    A Menzies Cone is used to separate crushed anthracite coal from rock. Inside the cone is slurry mixture of water and magnetite. The magnetite slurry has a high specific gravity. This allows the lighter coal to float, the rock and coal with a lot of rock in it sinks.

  • Sedimentary rock - Wikipedia

    The sedimentary rock cover of the continents of the Earth's crust is extensive (73% of the Earth's current land surface), but the total contribution of sedimentary rocks is estimated to be only 8% of the total volume of the crust. Sedimentary rocks are only a thin veneer over a crust consisting mainly of igneous and metamorphic rocks.

  • Coal, Kentucky Geological Survey, University of Kentucky

    Because coal undergoes physical and chemical changes as a result of increased heat, there is sometimes a misconception that coal is a metamorphic rock. Coal is a sedimentary rock. Coal is altered through biological and burial-thermal processes into different ranks. Many sedimentary rocks are also altered through burial-thermal processes ...

  • Specific Gravity and Bulk Density | Mining | SGS

    "Specific gravity" is the density of a material relative to water. Since rocks are comprised of several distinct mineral phases, they do not have a fixed specific gravity. Instead, a rock's "bulk density" arises as a result of the percentage of all minerals in a sample plied by the specific gravity of each.

  • University of Minnesota's Mineral Pages: Graphite

    As coal is almost completely composed of organic carbon, its metamorphism can produce large amounts of graphite-bearing rock. To a lesser extent, graphite is also found in some igneous rocks, igneous veins and pegmatites that are associated with metamorphosed graphite-bearing sedimentary rocks.

  • Coal, Kentucky Geological Survey, University of Kentucky

    The specific gravity of coal is important during coal cleaning because many of the common mineral impurities in coal have much higher specific gravity (density) than coal. For example, the specific gravity of pyrite (fool's gold), a common impurity in coal, and the main source of sulfur in coal, is 4.9 to 5.2. Because pyrite is much denser than ...
