Current changes in raw material purity and increasing product quality standards make understanding of impurity effects along the value chain and impurity control extremely topical. This short course covers sources of impurities in primary and secondary aluminum and their effects along the value chain. Impurities covered include trace elements such as sodium, calcium, nickel, vanadium, etc. Boride treatment for peritectic element removal, hydrogen effects and removal and demagging are included. Inclusion sources and inclusion removal methods are also covered.
The course will benefit smelter operators, technical personnel, alloy hardener, and other raw material suppliers. Users and suppliers of melt treatment technology such as degassers and filters will also find the course useful. Researchers interested in investigating impurity effects and developing new impurity removal methods will find the course useful grounding.

Stephen J. Lindsay
currently works as a senior smelting specialist for Alcoa. His background includes numerous technical and managerial capacities at Alcoa’s various smelting locations for more than 35 years. Linsday’s responsibilities include alumina quality, metal purity, electrolysis and bath, and fume control systems. He has published articles in Light Metals
, the proceedings of the Australasian Smelting Technology Conferences, and the proceedings of International Alumina Quality Workshops. Lindsay also has served TMS as the editor of Light Metals
and subject chair of Reduction Technology, as well as numerous other roles. He was awarded Best Paper for Reduction Technology in 2006 and 2009; has contributed to TMS industrial electrolysis courses and other short courses; and has served as an instructor for graduate programs at the University of New South Wales and the University of Auckland.
is Technology Director for Real Alloy, formerly a division of Aleris International. He has also worked for IMCO Recycling and Reynolds Metals Company during his career. Peterson received his Ph.D. in Metallurgy from the University of Utah in 1984. He has served in many areas of TMS, including as chair of the Aluminum Committee, Light Metals Division Chair, and President in 2009. His professional research interests include molten salt reactions, high temperature thermochemistry, reaction kinetics, heat and energy transport, and molten metal processing.
is the regional director for STAS Middle East. He received his bachelor of engineering in metallurgical engineering from McGill University and his MBA from University of Wollongong. Forakis has previously worked for Emirates Aluminium, Hatch, Rio Tinto Alcan, Noranda, and Alcoa. He was the subject chair for the Cast Shop sessions at the TMS 2015 Annual Meeting & Exhibition and a member of the technical committee of the Australasian Casthouse Technology Conference. He has held positions in operations, engineering, R&D, technical support, and business development.
