Aluminium Production Process: Challenges and Opportunities
metals Editorial Aluminium Production Process: Challenges and Opportunities Houshang Alamdari Aluminium Research Centre—REGAL, Université Laval, Quebec City, QC G1V 0A6, Canada; [email protected]; Tel.: +1-418-656-7666 Academic Editor: Hugo F. Lopez Received: 29 March 2017; Accepted: 6 April 2017; Published: 11 April 2017 Aluminium, with more than 50 Mt annual production in 2016, is an essential material in modern engineering designs of lightweight structures. To obtain aluminium ingots from bauxite, three main processes are involved: the Bayer process to produce alumina from bauxite; the anode manufacturing process to produce electrodes, and the smelting process using the Hall-Héroult technology. The Hall-Héroult process, involves the electrolysis of alumina, dissolved in molten cryolite to produce liquid aluminium that should be casted to produce ingots of different types of alloys. The technology is now about 130 years old and the aluminium production experienced a phenomenal growth during the past two decades—the highest growth rate for a commodity metal. The aluminium electrolysis cell is made of a steel shell, the internal surfaces of which are covered with a series of insulating linings made of refractory materials. The top lining, made of carbon, is in direct contact with the molten metal and acts as the cathode. The anode is also made of carbon, suspended in the electrolyte and consumed during electrolysis. According to the International Aluminium Institute [1] the energy required to produce one ton of aluminium varies between 12.8 and 16 MWh, depending on the technology used and the age of the smelters. Carbon consumption of the process—roughly about 400 kg of carbon for tone of aluminium—is also significant, contributing to the generation of about 1.5 tons of CO2 per ton of aluminium. -

Development of Iceland's Geothermal Energy for Aluminium Production
Development of Iceland’s geothermal energy potential for aluminium production – a critical analysis Jaap Krater1 and Miriam Rose In: Abrahamsky, K. (ed.) (2009) Sparking a World-wide Energy Revolution: Social Struggles in the Transition to a Post-Petrol World. AK Press, Edinburgh. Abstract Iceland is developing its hydro and geothermal resources in the context of an energy master plan, mainly to provide power for expansion of the aluminium industry. This paper tests perceptions of geothermal energy as low-carbon, renewable and environmentally benign, using Icelandic geothermal industry as a case study. The application of geothermal energy for aluminium smelting is discussed as well as environmental and human rights record of the aluminium industry in general. Despite application of renewable energy technologies, emission of greenhouse gases by aluminium production is set to increase. Our analysis further shows that carbon emissions of geothermal installations can approximate those of gas-powered plants. In intensely exploited reservoirs, life of boreholes is limited and reservoirs need extensive recovery time after exploitation, making geothermal exploitation at these sites not renewable in the short to medium term. Pollution and landscape impacts are extensive when geothermal technology is applied on a large scale. Background Iceland is known for its geysers, glaciers, geology and Björk, for its relatively successful fisheries management and its rather unsuccessful financial management. But this northern country also harbours the largest remaining wilderness in Europe, an endless landscape of volcanoes, glaciers, powerful rivers in grand canyons, lava fields, swamps and wetlands teeming with birds in summer, and plains of tundra covered with bright coloured mosses and dwarf willow. -
Anglesea Mine Hydrology and Hydrogeotechnical Study
Anglesea Mine Hydrology and Hydrogeotechnical Study Introduction Alcoa’s Anglesea mine is located at Anglesea, in south western Victoria, approximately 35 kilometres from Geelong. The Anglesea Mine supplied brown coal to the Anglesea Power Station since its inception in 1969 until shutdown in August 2015. The operation, including both mine and power station, has now entered an interim monitoring period whilst the final Closure Plan is being developed prior to implementation. The mine is located within the Anglesea River catchment, a relatively small scale river system, with a catchment area of approximately 885ha. The two main tributaries of the Anglesea River are Marshy Creek, which flows from the north, and Salt Creek which flows from the west with its last kilometre diverted around the northern edge of the Alcoa mining area prior to the commencement of mining in the 1960’s. Alcoa has a legislative requirement to manage and ensure risks related to the mine are minimised to acceptable standards. Sources of potential risks may include mine hydrology, hydrogeotechnical, geotechnical, erosion, fire, impacts on internal/external infrastructure, site and public safety, and impact on environmental elements such as creeks and waterways. Background The Work Plan requires a Closure Plan that depicts the final landform at the cessation of mining to comprise a final lake void surrounded by safe and stable batters and revegetated areas. The plan also depicts the re-diversion of Salt Creek approximately back to its original path. With the operation shutdown, the closure concept for the Mine Closure Plan now requires technical specification, and therefore a technical study of the proposed hydrology and hydrogeotechnical aspects is required. -

Concluding comments 18 References 20 Appendix 1 Ownership of primary aluminium production in Australia 22 Appendix 2 Aluminium cash price, 1990-1997 25 The Australia Institute 2 Executive summary The aluminium smelting industry accounts for 16% of greenhouse gas emissions from the electricity sector and 6.5% of Australia’s total emissions (excluding land-use change). The aluminium industry has been a strident voice in the debate over climate change policy and has led industry resistance to effective measures to cut emissions. The industry argues that it is of great economic importance to Australia, especially for the foreign exchange its exports earn. It frequently threatens governments with the prospect of closing down its Australian smelters and moving offshore if it is forced to pay higher prices for electricity as a result of climate change policies. Since the Kyoto Protocol was agreed in December 1997, it has argued that the burden for cutting emissions should be placed on other sectors of the economy and households rather than being distributed equally across polluting sectors. -
