This method can be used to separate coal and rock waste on the basis of density. The jigger described here is a small-scale model of a method used industrially. Jigging is accomplished by filling the apparatus about one-fifth full of 2 to 5 mm coal / 'rock waste' mixture and plunging the jigger up and down in a bucket nearly full of

The equipment most frequently used in these plants is designed to separate the coal from reject materials, and incorporates methods that make use of the difference in specific gravity between the coal and host rock. Most of the coal that is cleaned is deep-mined bituminous coal.

-clast size (how big fragments/grains are making up the rock) -clast composition (rock fragments or individual mineral grains)-angularity (spherical or no)-sorting (degree to which the coasts in a rock are all the same size or different)-character of cement (can be either quartz or sometimes is calcite)

The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2 ...

A spoil tip (also called a boney pile, gob pile or culm bank) is a pile built of accumulated spoil – waste material removed during mining. These waste materials are typically composed of shale, as well as smaller quantities of carboniferous sandstone and various other residues. Spoil tips are not formed of slag, but in some areas they are referred to as slag heaps.

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back ...

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...

Kenya's progress will not be slowed down by not investing in dying tech like coal. The Great Rift Valley provides Kenya with one of the greatest potential resources of geothermal energy, and northern Kenya is great for wind energy (they just recently built a 310MW wind farm there). And of course nuclear is .
