Aluminium Production: Processes and Environmental Impact

This lecture covers the primary metallurgy of aluminium, focusing on the Hall-Héroult electrolysis process for aluminium production from alumina. It discusses the challenges of reducing alumina, the environmental aspects of aluminium production, and the potential for improving efficiency through inert anodes. Alternative aluminium production methods and the importance of aluminium recycling are also explored. The lecture further delves into powder metallurgy, detailing the process, advantages, disadvantages, and applications of producing metal parts through this method.
