Présentation de l'éditeur

This book has been compiled for the purpose of giving a systematic description of modern practice in the art of coal washing. This may appear at first glance to be much easier than it really was.

Only a study of the chronological development of the art of coal washing will enable us to make a judicious selection of equipment. An effort is here made to set up a proper or standard rule for guidance in the present as well as the future, from a survey of the experience of the past, with its mistakes and blind alleys, its round
