Chapter 7 COAL Pennsylvania State University

FIGURE 7-3. Variation of selected coal properties with coal rank. The chemical approach to characterizing coals is to determine the amounts of the principal chemical elements in them. In the jargon of the coal business, this procedure is called the ultimate analysis of coal. Carbon and hydrogen are the principal combustible elements in coal.

What are the types of coal? USGS

There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon rich, and harder material. The four ranks are: Anthracite: The highest rank of coal.

Moisture in Coal, Coal Analysis, Kentucky Geological

Residual moisture: Moisture (water) remaining in coal after air-drying a sample and minor heating in a moisture oven to 10 to 15°C (depending on coal rank) above room temperature (ASTM method D121-09; American Society for Testing and Materials, 2013, p. 355–368). It is recorded on an as-determined basis (denoted as “ad” or “AD”).

Rank and maceral effects on coal dust generation

Apr 01, 1979· Hshieh's [12] work on the grindability of coal also indi- cated that grindability changes with coal rank and that for a specific rank of coal the grindability of the hetero- geneous coal varies as the chemical composition of the coal. Hshieh [12] hypothesized that rank, petrographic constituent and mineralogy influence coal grindability.

Whole-coal measurements of coal rank were used long before maceral-specific indicators such as vitrinite reflectance. The three traditional measurements are proximate analysis, ultimate analysis, and calorific or heating value.Each of these is used in various international standards

Editorial for Special Issue “Mineral Liberation”

The mineral liberation studies are fundamental for mineral processing and metallurgy. Mineral resources are non-renewable, and it is expected that the ore grades available to the mining industry will decrease in the future [].Thus, mineral processing must meet sustainability criteria, that is, to recover the greatest amount of materials possible from the resources we have.
