Paperback. Condizione: New. Print on Demand. This book delves into the nature of water in coal. Coal, like other organic matter, contains water in its composition. However, the state of this water within coal differs from ordinary water. A part of the water in coal has a vapor pressure below normal, and the energy changes involved in its combination with or separation from the coal substance are unique. This book explores these properties, examining how different types of coal contain different percentages of water with varying vapor pressures. The author explains how certain factors, like humidity and coal size, affect the coal's weight. They also delve into how the inherent water in coal generates heat upon contact with dry coal and other liquids, providing insights into the colloidal nature of part of the coal substance. This book offers valuable insights into the properties of water in coal, making it an indispensable resource for scientists and professionals in coal research. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. …

Paperback. Condizione: New. Print on Demand. This book compiles articles published in the Mining and Scientific Press between 1915 and 1920. Five of these articles were reprinted in a book on the flotation process in 1916, and seventeen more were included in a book on the same topic in 1917. Those books quickly sold out, and no similar books have been published since to meet the needs of those working with or learning about flotation. The articles cover the history of flotation, flotation principles, the use of flotation in concentrating gold and silver minerals, and both legal and testing considerations for flotation. The author hopes that this compendium will aid those seeking to improve their understanding of and work with the flotation process in the concentration of ores.
