Uses of metals have been projected along with their backward linkages with history, recovery from minerals and particular sets of physical/chemical characteristics and with their forward linkages with the status and trends in waste utilization and substitution wherever relevant. Apart from extraction of metals, the direct industrial uses of the metallic minerals and the specifications with emphasis on the principles and reasons have also been discussed. In this book, the 12 metallic minerals, 29 metals and 6 metalloids that are important in today's ecomy, have been brought within one cover. Some of the information incorporated in it are t ordinarily accessible to many, but have been obtained by the author through personal contacts with the industries during the last 35 years. The book presents a highly technical subject in an easily understandable logical fashion.
