About this book
The trace elements in coal play an important role in its mining, treatment and usage. This book is a unique blend of relevant information on the 24 trace elements of environmental interest. Major emphasis is on background matters (content, geology, modes of occurrence) and to practical aspects (beneficiation, combustion, effects in emission control systems). Other topics dealt with in detail are the transport and dispersion of plumes, deposition from the atmosphere around a power station, leaching from coal ash, and mineland reclamation. In contrast to other publications, this book is an up-to-date, balanced account of the overall situation. This book is suitable for coal scientists and technologists involved in the environmental aspects of coal production and use, and regulatory bodies.
