This collection of symposium papers covers a wide range of topics on rock fragmentation, from carefully documented case studies to attempts, for example, at fractal representation of the fracture process itself.

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.

This textbook presents a thorough overview of chemical and process industries. It describes the standard technologies and the state of the industries and the manufacturing processes of specific chemical and allied products. It includes examples of industries in Ghana, highlighting the real-world applications of these technologies. The book introduces new developments in the processes in chemical industry, focuses on the technology and methodology of the processes and the chemistry underlying them. It offers guidance on operating of processing units. Furthermore, it includes sections on safety and environmental pollution control in industry. With a pedagogical and comprehensive approach, utilizing illustrations and tables, this book provides students in chemical engineering and industrial chemistry with a concise and up-to-date overview of this diverse subject.

Vol. 6 includes reports of cases dealing with national insurance and general insurance (other than marine).
