Process Involved In Minerals Coal - Logan Sainlez
Coal mining is the process of extracting coal from the ground coal is valued for its energy content and since the 1880s has been widely used to generate electricity steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production .

4 Coal Mining and Processing | Coal: Research and ...
The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7) …

For this reason, any process used to convert coal to alternative fuels must add hydrogen (either directly or in the form of water). Gasification refers to the conversion of coal to a mixture of gases, including carbon monoxide, hydrogen, methane, and other hydrocarbons, depending on the conditions involved. Gasification may be accomplished either in situ or in processing plants.

Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals.This process is often known as "Coal to X" where X can be many different hydrocarbonbased products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).

Tailings are the often-toxic residue left over from the process of separating coal from gangue, or economically unimportant minerals. Toxic coal tailings can pollute local water supplies. To miners, the dangers of underground mining are serious. Underground explosions, suffocation from lack of oxygen, or exposure to toxic gases are very real...

How Do Diamonds Form? | They Dont Form From Coal!
Is coal involved? Coal is not a probable carbon source for this diamond-forming process. The most likely carbon sources from the subduction of an oceanic plate are carbonate rocks such as limestone, marble, and dolomite, and possibly particles of plant debris in offshore sediments.
Coal Geology | Geoscience Australia
Coal is a combustible sedimentary rock formed from ancient vegetation which has been consolidated between other rock strata and transformed by the combined effects of microbial action, pressure and heat over a considerable time period. This process is commonly called ‘coalification’.

Smelting involves heating the ore to a very high temperature, often in a blast furnace. A reducing agent is usually added and the mineral is removed using stone reactions. In modern times several new techniques are used to extract the mineral from the ore, in addition to smelting.

Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. Primary crushers are commonly designed to operate 75% of the available time, mainly because of interruptions caused by insufficient crusher feed and by mechanical delays in the crusher.
