This textbook is the first to offer essential information on the ores and basic properties of the majority of chemical elements, together with the most important industrial minerals, their latest applications and recycling options, illustrated with a wealth of photos.    This book represents the culmination of a comprehensive project jointly pursued by the Valentí Masachs Geology Museum and the Universitat Politècnica de Catalunya (UPC) (Polytechnic University of Catalonia) over the past several years. Published in response to multiple requests from university professors and other educators, it will promote a new society in which human beings use the Earth's natural resources responsibly and with respect for the environment.    Keep in mind that we aren't the only inhabitants of the Earth, a wonderful but depletable planet!
