Coal is used industrially for many purposes. Because coal is a highly variable product its use is dependent on the individual properties of a coal bed or part of it.
Coal beneficiation, the sizing of coal and the removal of higher specific gravity fractions of the raw coal, is a first step in many utilization processes. Coal beneficiation employs various methods to improve coal quality for a particular industrial application, for example, for the production of metallurgical coke or the production of a lower sulfur content for combustion. The most important methods of these include heavy-media washing to remove mineral matter (Leonard, 1991).
Figures & Tables
This volume of the “Atlas of Coal Geology” provides 393 images on various subject matters related to coal deposits and coal resource utilization. The supporting text provides an introductory overview of coal exploration, mining, and coalbed methane (CBM) development, followed by discussions on various megascopic aspects of coal geology (microscopic aspects are covered in Volume 2). Because of the vast subject matter, many generalities had to be made in the text. References are included to guide those interested to more detailed discussions. All citations within the document are linked to the detailed reference list for this volume. The overriding theme for this publication is that a picture is worth a thousand words.
