Due to its antimicrobial and antiseptic properties, silver loaded activated carbon is used as an adsorbent for purification of domestic water. Drinking water can be obtained from natural water by treating the natural water with a mixture of activated carbon and Al(OH) 3, a flocculating agent .
Coking coal is essential to the manufacture of blastfurnace coke and foundry coke, which is used in steel production. Coking coal is characterised by its low volatile matter content and high swelling index. Based on its properties, coking coal can be divided into two groups:. semisoft coking coal (or SSCC) ; hard coking coal (or HCC) ; Hard coking coal has better coking properties than semi ...

Comparative Properties of Bituminous Coal and Petroleum Coke as Fuels in Cement Kilns. ... The use of petroleum coke may be limited by its high sulfur content. Technological measures such as finer grinding, precalciners designed to have a higher retention time, an external combustion chamber before the calciner, a special highmomentum kiln ...
Gravity Separation / Separation of gravity: Gravity separation is a mineral separation process based on the density difference between particles and particles of ore impurities. Froth Flotation / Separation flotation: Froth flotation is a separation process ore from mineral impurities by way of float ore to the surface through binding to the froth.
Steam coal also known as thermal coal is mainly used in power generation. Coking coal also known as metallurgical coal is mainly used in steel production. Other important users of coal include alumina refineries, paper manufacturers, and the chemical and pharmaceutical industries.
Comparative Properties of Bituminous Coal and Petroleum Coke as Fuels in Cement Kilns. Bituminous coal has been in use as fuel in cement kilns for a long time. With coal costs continuously rising, cement plants have been looking for alternative less expensive fuels.
The interaction of coal properties and coal utilization begins at the mine face. The breakage of the coal in mining influences its subsequent beneficiation. Beneficiation is fundamental to the proper combustion of coal and is vital to the preparation of the feedstock for the production of metallurgical coke.

COAL MINING World Coal Association known as 'retreat mining', where coal is mined from the use very large pieces of equipment
Fractional distillation is the separation of a mixture into its component parts, ... Some of the factors involved in design calculations include feed load size and properties and the type of distillation column used. The two major types of distillation columns used are tray and packing columns. Packing columns are normally used for smaller ...
NETL's inhouse research efforts on obtaining rare earths from coal and coal byproducts begins by sampling, analyzing, and characterizing the nation's supply of coal. While the name "rare earths" might imply a scarcity of these elements, they are fairly plentiful in the Earth's crust.
Download Citation on ResearchGate | Magnetitecoal separation by continuous HGMS | Magnetite, slurried in water, is used to create an apparent heavy medium in which fine coal ( to mm) is cleaned of its mineral impurities.

Clean coal technologies, coal cost and quality, environmental considerations, sustainable development, the growth of the South African economy and Government's regulation of the electricity industry are the main challenges to the continued use of coal as South Africa's primary energy source.
Availability: Bituminous coal is abundant. More than half of all available coal resources are bituminous. Mining locations: In the, bituminous coal can be found in Illinois, Kentucky, West ia, Arkansas (Johnson, Sebastian, Logan, Franklin, Pope, and Scott counties), and locations east of .
Coal is classified based on certain gradational properties that are associated with the amount of change that the coal has undergone while still beneath the earth. The categorization shows select chemical and physical properties that assist in understanding how the coal will .
Various phenolic coal tars have the properties of a painkiller. Coal tar is used to protect and beautify the underlying pavement. Coal is also used to make parking lot seal – coat products. Roads are made with the use of coal tar. Coal tar is flammable in nature. Hence, it is used for heating.

In 1999 the EU used half of its coal fly ash and bottom ash in building materials (where fly ash can replace cement), and it used 87% of the gypsum from flue gas desulfurisation. Carbon dioxide from burning coal is the main focus of attention today, since it is implicated in global warming, and the Kyoto Protocol requires that emissions decline ...
The ability to blend different types of coal enables some coals which do not coke well to be used with higher grade coals to form an acceptable mix. Developments in blast furnace technology (pulverized coal injection in particular) have also allowed lower quality coals to be used in steelmaking in place of a portion of the coke.
