期刊介绍： International Journal of Coal Preparation and Utilization publishes original research papers, short communications, review articles, book reviews, and symposium announcements covering all aspects of coal preparation. The journal is significant reading for all individuals involved with coal preparation, including those in operations, engineering, management, education, and scientific research. Topics include: coal properties and coal petrography; coal quality and characterization; surface chemistry of coal and minerals; crushing, grinding and liberation; coal screening and classification; dense medium and density separations; froth flotation and oil agglomeration; process control and optimization; flocculation and thickening; dewatering and thermal drying; briquetting and pelletizing; coal handling and storage; coal utilization and blending; waste disposal and pollution; utility waste product utilization; and carbon based material. Additional subjects covered by the journal include properties of coal/water and coal/oil slurries as well as the processing of oil shales and tarsands by physical and physiochemical methods.
