2020/7/30· Metallurgical Coal Metallurgical coal differs from thermal coal, used for energy and heating, by its carbon content and its caking ability. Caking refers to the coal''s ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces.
This type of coal briquette is primarily used for heating in China and South-Korea, but also for cooking, e.g. in Vietnam. In some areas, where coal is scarce, coal dust is used in a mixture with dung, formed to cakes and dried in the sun, as shown in the picture.

In fact, if we keep our coal dust with certain moisture and put them in a place for 8-24 hours, the sodium humate will be produced by the coal dust and even the coal can be briquette without binder. Also for some of the coals, there appear clays which are a very good binder for coal briquette, we can also briquette those coals without adding other binders.

A rapid, simple method based on graphite furnace atomic absorption spectrometry is described for the direct determination of arsenic in coal fly ash. Solid samples were directly introduced into the atomizer without preliminary treatment. The direct analysis method was not always free of spectral matrix interference, but the stabilization of arsenic by adding palladium nitrate (chemical
