Lignite coal is softer than bituminous coal, with a Hardgrove grindability index (HGI) in the range of 100 making it easier to pulverize. As like any other coal, lignite coal is also an organic rock (as opposed to most other rocks in the earth's crust, such as clays and sandstone, which are inorganic).
Hint: Coal is classified into four main types: anthracite, bituminous, subbituminous, and lignite. The types of iron ores which are used are; hematite, magnetite, limonite and siderite.

Lignite is brownish-black in color and has a carbon content around 60–70 percent, a high inherent moisture content sometimes as high as 75 percent, and an ash content ranging from 6–19 percent compared with 6–12 percent for bituminous coal. Thus first lignite (also called "brown coal"), then sub-bituminous coal, bituminous coal, and lastly anthracite (also called "hard coal" or "black ...

The coal is a hard cannel, filling a basin in the Second Magnesian Limestone; the ores occur in seams, seldom more than an inch in thickness, in the joints of the coal. The ore incidentally obtained in mining the coal afforded an occasional shipment to the smelters. Vanadium is found in a lignite coal in the province of Mendoza, Argentine Republic.

Bituminous Coal or black coal is a relatively soft coal containing a tarlike substance called bitumen. Bituminous Coal is of higher quality than lignite coal but of poorer quality than anthracite. Bituminous Coal was usually formed as a result of high pressure on lignite. Bituminous Coal is an organic sedimentary rock formed by digenetic and ...

Coal is the most widely distributed fossil energy resource in the world. It is mainly divided into bituminous coal and anthracite, sub-bituminous coal and lignite. Sixty percent of the world's recoverable coal reserves are concentrated in the United States (25 percent), the former Soviet Union (23 percent) and China (12 percent).
Answer (1 of 2): I would have to say it would be difficult. From a book I have "Coal The Energy Source of the Past and Future", Harold Schobert, ACS (1987), and taking some info I posted for another coal question, quoting from the book: > The geochemical phase of coalification is, in essence, t...
Bituminous: Even greater pressure results in the creation of bituminous, or "soft" coal. This is the type most commonly used for electric power generation in the U.S. It has a higher heating value than either lignite or subbituminous, but less than that of anthracite. Bituminous coal is mined chiefly in Appalachia and the Midwest.
Bituminous coal generally looks more dull, while anthracite is more shiny, almost like a piece of black onyx. If you rub your hand on a piece of bituminous, it will leave a black mark. Anthracite, generally, will leave no mark. If you put a piece of bituminous on a rock and hit it with a hammer, it will make a "thump" sound when it breaks.
Coal rank: The classification of coals according to their degree of progressive alteration from lignite to anthracite. In the United States, the standard ranks of coal include lignite, subbituminous coal, bituminous coal, and anthracite and are based on fixed carbon, volatile matter, heating value, and agglomerating (or caking) properties.
Coal is primarily made of Carbon, Hydrogen, Oxygen, Nitrogen, Sulphur and varying quantities of aluminium, zirconium and many other minerals. In terms of increasing carbon content, hardness, heat content and decreasing moisture coal is of three types viz. Lignite, Bituminous and Anthracite. Further, Peat, first step in formation of coal.
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 U.S. rank classification, lignites are defined based on calorific value. Lignites have calorific (heating) values less than 8,300 Btu/lb (ASTM, 2014).
An organic sedimentary rock contains high in volatile matter, less carbon than anthracite. Bituminous is it the most abundant and most-used type of coal. This type of coal contains between 50% - 80% carbon, 20%-40% volatile matter. It has high calorific value and therefore, mainly used for thermal power stations and chemical industries.
Anthracite is a type of coal with a highest rank. Coal rank measures the carbon content which is in correlation with calorific value and metamorphic grade. It has a very high carbon (over 90%) and low volatile content (below 5%) 1. Anthracite is a shiny black rock. Width of sample is 8 cm. Location unknown, either Russia or Ukraine.
SIC Code 1221 - Bituminous coal and lignite surface.

Snapshot. SIC Code 1221 - Bituminous Coal and Lignite Surface Mining ...
Bituminous coals are black, shiny, and generally hard.They are a medium-rank coal. Bituminous coals generally have calorific values above 11,500 Btu/lb and volatile matter below 14% (ASTM, Jackson, 1997). In the Illinois Basin (and western Kentucky), however, the lower rank end of what are termed bituminous coals in the United States have calorific values of 11,100 to 11,300 Btu/lb.
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 Origins: indonesia,australia,iran,russia,colombia

This coal has been buried deep and subjected to increased temperatures. It is the most popular coal in commercial use. Metallurgical coal is high grade bituminous coal which has a special value for smelting iron in blast furnaces. (iii) Lignite: It is a low grade brown coal, which is soft with high moisture content.

Coal is basically a carbonate sedimentary rock. Coal is a source of power. On the basis of iron contained, coal is classified as peat, lignite, bituminous and anthracite.
