OSTI ID:7211577

This study assesses the likelihood of new process technology and new practices being introduced by energy intensive industries and explores the environmental impacts of such changes. Volume 8 deals with the alumina/aluminum industry. The report examines three new process developments for producing alumina from domestic clays as alternatives to the Bayer process: (1) nitric acid leaching process, (2) hydrochloric acid leaching process, (3) clay chlorination (such as the Toth alumina process), and two process changes for the production of aluminum: (1) the Alcoa chloride electrolysis process and (2) the application of titanium diboride cathodes to the conventional Hall-Heroult cells. All of these alternatives are discussed in terms of relative process economics and environmental/energy consequences.
