Supply and Competition in Minor Metals [EPUB ebook] 

An interest in the minor metals — termed "minor" as their annual production is relatively small — had been developing for many years. This study, first published in 1965, examines patterns of supply that can be identified as underlying the production of minor metals, and then uses these patterns to investigate the nature and degree of competition in the production of minor metals. This book will be of interest to students of environmental studies.
