Excerpt from Handbook of Ore Dressing, Vol. 1: Equipment and Practice In the following pages an attempt has been made to cover, in condensed form, the various stages in the mechanical handling and preparation of an ore for metallurgical treatment. Amalgamation, concentration, flotation, chemical solution, and smelting - by which either a metal or a mineral is extracted from an ore or concentrate - are considered as essentially metallurgical processes, deserving of specialized treatment, and outside the scope of the book. A line of demarcation between ore dressing and metallurgical extraction and recovery is proposed which, it is hoped, may be found acceptable, as aiding in the more precise interpretation of terms, and the better classification of data. Information and illustrations have been obtained from a variety of sources, and a bibliography is appended. Appreciative acknowledgment is made to those mentioned, as well as to the publishers, and apologies are tendered to any whose names have been inadvertently omitted. The aim has been to supply a handy and practical vade-mecum for millmen and engineers. The author shares that fallibility which almost invariably characterizes an effort of this kind. He will welcome and appreciate constructive criticism and comment, and the disclosure of any errors that may be noticed.
