Excerpt from Metallurgy of Copper My aim in preparing this book has been to furnish a treatise on copper which will meet the demands of the metallurgist of May. In order to do this, it has been necessary: to present the leading physical and chemical facts about the metal, its alloys, and its compounds which are of metallurgical importance; to record from the Older practice that which is of lasting value; and to give the details of the present modes of operating. Though we have several books treating Of certain branches of the metallurgy of copper, such as the valuable volumes of Peters, Greenawalt, and others, there does not exist a modern book which covers the entire ground as the present work aims to do. In the study of processes there are given the principles and the practice. The discussion of principles is confined to the essential points; for an ex tended presentation the reader is referred to my treatise on General Metallurgy. The examples Of practice are drawn mainly from the United States. The text and footnotes will show that the technical literature on copper has been covered. The details of practice, not recorded in print, have been obtained through visits to and detailed studies of the leading copper smelteries and refineries of the United States; additional information has been available through correspondence. The tables giving the working data of the leading plants of the United States, Canada, Mexico, Germany, and Australia show the extent Of the field which has been covered.
