Excerpt from The Industries of Russia, Vol. 5: Siberia and the Great Siberian Railway; With a General Map Oi that great expanse of territory reaching all the way from the Ural mountains to the Pacific Ocean and from the Frozen seas to the borders of the Celestial Empire there is perhaps little more than the name, Siberia, authentically known to the general public. Yet With its Wide-stretching plains, its magnificent water systems and its unknown wealth of noble metals and other valuable mineral de posits buried in its bosom, there is for such a land a future too great to be overlooked at the present day.

Excerpt from The Industries of Russia Therefore, case and gender endings, particularly of adjectives, have been dropped. To illustrate, the very common adjective terminations, ckoü, cnan, ckoe (skoi, skaTa, skole), used to designate the genders, have been shorn of their final vowels, and the reader will consequently find such expressions as the Dombrovsk Mining School, instead of the varying forms, Dombroffsky, Bombrqfsky, Dombrowski, Bombrovskt, or DombrovskaU Mining School. However, such proper names as have become fixed with any degree of uniformity in English books have been retained in their familiar dress, although the orthography be erroneous, as Kirghiz for Kirgiz, and Ural mountains for Ural mountains. In this connection I wish to call attention to the list of errors to be found at the end of this work, and to say, as in the Preface to Manufactures and Trade of Russia of this series of volumes, that this translation has been made in very great haste, and that the typographical work has been done by casemen unfamiliar with the English language, thus making it extremely difficult to avoid errors. In this instance, however, the more important mistakes of this kind, especially such as were apt to be misleading, have been corrected in the table of Errata at the close of the volume. In presenting this translation of the Mining and Metallurgy of Russia to the visitors of the Worlds Columbian Exposition at Chicago, I feel confident that the authentic information contained in these pages will be of practical value to those who are interested in the great mining industries of the United States; and it was in this conviction that I accepted the labour of this Edition.

The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.
