"Extractive Metallurgy of Niobium" presents an account of the metal through 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 growth and development witnessed in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. This book presents an account of the metal through its comprehensive discussions of properties and applications, and resources and resource processing.
