Lignite is the lowest rank of coals. Lignites are brown in color and have an earthy, crumbly texture. They look more like dirt, than what people normally think of when they think of coal. In the rank classification, lignites are defined based on calorific value. Lignites have calorific (heating) values less than 8,300 Btu/lb (ASTM, 2014).

Recommendation: There should be renewed support for advanced coal mining and processing research and development to optimize use of the nation''s coal resources by increasing the amount of coal that is economically minable through technological advances that .
Coal Flotation with NonIonic Surfactants. In coal flotation, the most commonly used collectors are oily materials collectors such as diesel oil and kerosene. For higher rank coals, the reagent consumption in flotation is low because of the high natural hydrophobicity of the coal.
Mineral contentCoal contains a variety of minerals in varying proportions that, when the coal is burned, are transformed into ash. The amount and nature of the ash and its behaviour at high temperatures affect the design and type of ashhandling system employed in coalutilization plants. At high temperatures, coal ash becomes sticky (, sinters) and eventually forms molten slag.

composition and rank of a coal allows the petrographer to predict coke stability by using the coke strength correlation curve. This technique is particularly appropriate for the prediction of Micum 10 values (M10). Therefore coal petrographic analysis is an extremely useful tool for the identification of suitable coking coals. As a consequence it
