Description

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility.

The favor which the first edition of the present treatise on Roasting of Ores was received by the mining public, and the increased inquiries after a new edition, induced the author to write the present book.

During the long interval of ten years which elapsed since the first edition, many improvements in the construc tion of furnaces, as well as in the way of roasting, have been introduced; this edition, therefore, has undergone many alterations.
