Publisher's Synopsis
Excerpt from A Treatise on Metalliferous: Minerals and Mining
IN revising this book for the Fifth edition, I have endeavoured, while making additions wherever they seemed to be necessary, to keep within the original design of the work as laid down by my father in the Preface to the First edition. The advances made in the knowledge of particular minerals, and of their distribution throughout the globe, as well as in the adaptation of processes and machinery for the treatment of ores, since the book was first written, have necessitated the insertion of much additional matter, increasing the volume by nearly 100 pages. Thus, recent experiences of the Treatment of Refractory Gold Ores, and the later development of the processes of Concentration and Chlorination, have been fully noticed; while (besides the enlargement of existing chapters) two new chapters - on the Treatment of Zinciferous Ores and the Sale and Sampling of Lead Ores - have been added. About twenty new illustrations are also given. I trust that these new features will be found to enhance substantially the value and utility of the work.
