摘要: Publisher Summary This chapter discusses the modes of occurrence inorganic elements in coal, both as mineral phases and organically bonded elements. The effects that highly dispersed may have on coal processing are also reviewed chapter. Mineral matter plays a variety important roles all utilization processes. Inorganically bound present-day coals result at least five mechanisms operating or from time initial peat deposition: (1) incorporation original plant material; (2) precipitation aqueous solution; (3) accumulation airborne detritus; (4) waterborne (5) epigenetic mineralization, is, minerals formed cleats fractures deposit. Accumulation detrital particles chemical dissolved species solution major processes by which introduced into deposit external sources.
