Resumen
Coal is a remarkably complex combination of macerals and minerals and inorganic elements in organic associations plus liquids, gases, and semi-solid organics, all overprinted by coal metamorphism. The proper characterization of coal is necessary for academic research on coal origins and utilization and for the current and future industrial utilization of coal and coal by-products. A coal analysis scheme must be comprehensive because no one petrographic or chemical analysis stands alone. Coal rank, for example, can be expressed as vitrinite reflectance, a petrographic parameter, or by a number of chemical parameters, such as heating value or carbon content. No one parameter is reliable from lignite to meta-anthracite and, even at a single rank level, variations due to the maceral content and aspects of the organic chemistry imply that a view of more than one parameter is necessary to determine the coal rank.

Over the course of the ca. 170 years of combined experience in coal science between the authors, many people have influenced our views of coal analyses. Other than his co-authors on this paper, among Hower's influences, he counts Norm Suhr, Alan Davis, and Peter Given at Penn State; John Kuhn, Gerald Thomas, Shelley Hopps, and Tonya Morgan at the Center for Applied Energy Research (CAER); Dave Robertson at the University of Kentucky and later the University of Missouri; Bill Lloyd and John Riley at Western Kentucky University (WKU) (Lloyd was at the CAER prior to becoming a dean at WKU); Leslie Ruppert and Allan Kolker at the U.S. Geological Survey; and Leroy Jacobs and Jane Thomas of Wyoming Analytical Laboratories. On-going discussions, usually over long distances, with Dal Swaine, Yakov Yudovich, Greta Eskenazy, Shifeng Dai, Vladimir Seredin, and Colin Ward focused his views of coal geochemistry and mineralogy. Ralph Gray influenced his studies of Hardgrove grindability. Richard Winschel (CONSOL) and John Popp (Alliance Coal and later at Natural Resource Partners) taught him the importance of looking to the needs of industry, not just academia. Discussions with the many students (from high school through graduate school), co-workers, and visiting scholars passing through his laboratory developed the views of coal petrology and coal science seen in his published work. Finkelman benefitted from discussions with many USGS colleagues including Irv Breger, Blaine Cecil, Ron Stanton, and Peter Zubovic, collaborations with Harvey Belkin, Linda Bragg, Allan Kolker, Bill Orem, Curtis Palmer, and Hal Gluskoter (Exxon and later at the USGS) had a significant positive impact on coal research and his career. Others with whom he benefitted from discussions and collaborations include Sergei Arbuzov, Shifeng Dai, Dan Casagrande, Greta Eskanazy, Fred Price, Glenn Stracher, Yugang Tang, Vladimir Seredin, and Baoshan Zheng. To all these and more he owes a debt of gratitude. Arnold also counts Peter Given at Penn State as one of her heroes. His course on organic geochemistry especially related to sulfur in coal has played a role in her understanding of the chemistry, especially the surface chemistry, of coals. Dr. Arnold also had the opportunity to work with Ralph Gray on coal petrology related to samples for her M.S. Thesis, which was funded by US Steel Research– Coal froth flotation: The effects of petrological and mineralogical constituents. She credits Alan Davis (Penn State) for his contributions to that work as a member of her committee. Her coal and mineral processing expertise was first developed through course work and research at Penn State with Peter Luckie (“there is no such thing as coal, there are coals”), Richard Hogg, and Leonard Austin, along with adjunct faculty member Richard Klimpel. Her experience at the Electric Power Research Institute's Coal Cleaning Test Facility (later CQ Inc.) shaped her knowledge of coal handling and blending related to coal preparation. Above all, she credits her dedication to coal preparation, especially froth flotation, and to the mining industry to her mentor and thesis advisor, Frank F. Aplan. Without his guidance in surface chemistry related to clays and coals, she would not have developed the understanding of the role of water quality and the importance of all mineralogic and petrologic components in coals as well as their application to other minerals. While this essay was not directly supported by any of the US Department of Energy's CORE-CM projects, our work on several of these projects and the conversations with individuals involved on all of the projects has made us more fully appreciate the renewed interest in coal and coal products as a source of critical elements and advanced materials. We are keenly aware of the need for an understanding of the complex properties of coal and the appreciation of the array of tests employed to analyze those properties.
