In the primary production process alumina (aluminium oxide) is produced from bauxite and further processed to aluminium via electrolysis. Secondary aluminium is refined or remelted from scrap. Further processing of aluminium includes casting, rolling and extrusion operations. Cogeneration facilities can be found in three out of eight alumina producing installations (of which five are in operation). There are two aluminium plants with own electricity production in the UK. In addition, electricity production may also be outsourced. In order to acquire information and data on the aluminium sector, the Fraunhofer Institute for Systems and Innovations Research (ISI) is in contact with Eurométaux and the European Aluminium Association (EAA). In Annex I to the amended Directive on the EU ETS 1, aluminium production is divided into primary and secondary production. Further processing of aluminium such as alloy production, refining, foundry casting, etc. are considered with a common NACE code together with further processing of other non-ferrous metals. Table 1 gives an overview of the classification of these Annex I activities. Table 1 Division of the aluminium industry according to Annex I to the amended Directive and corresponding activities in NACE Rev. 1.1 classification Annex I category of activities NACE code Description (Rev. 1.1) (NACE Rev. 1.1) Production of primary aluminium 27.42 Aluminium production Production of secondary aluminium where combustion units with a total rated thermal 27.42 Aluminium production input exceeding 20 MW are operated Production and processing of non-ferrous metals, including production of alloys, refining, foundry casting etc., where 27.53 Casting of light metals combustion units with a total rated thermal input (including fuels used as reducing agents) exceeding 20 MW are operated. Information on the number of aluminium production installations included in the ETS has been provided by the European Aluminium Association2. An overview is given in Table 2. From the data given in Table 2 it is obvious that all primary smelters have a cast house attached. 1 Non-ferrous metals were not specified in Annex I to the original Directive. 2 Personal communication, EAA via e-mail, 15 th of May 2009 1 Table 2 Overview of installations included in the EU ETS; including installations in Norway and Iceland (EAA, 2009) Activity Number of ETS Notes installations Bauxite mining 2 Not included in the ETS.

In terms of production volume (t) the fraction within EU ETS could be 40-50% according to the Organisation of European Aluminium Refiners and Remelters (OEA). 3 Double counting of remelting and rolling installations. Exact emissions data for the years 2005 – 2007 are not available as non-ferrous metals activities were not included in the EU ETS. An approximate estimation has however been provided by the EAA 3. The approximate GHG emissions given in Table 3 are calculated using a weighted average of the range of direct emission factors for the European installations and shall provide a first impression of the GHG emissions for lack of the exact values that may be derived from benchmarking curves.

The approximate power consumptions given in Table 4 (see next page) are calculated using the weighted average of the range of specific electricity consumption of European installations and shall give an idea of the magnitude of electricity use. It must be underlined that the main focus of this report is on direct emissions from the aluminium chain within the EU ETS. However, as primary aluminium production is one of the large electricity consumers and hence possibly concerned by compensation mechanisms for indirect effects of the ETS via the inclusion of allowance prices into the electricity prices, the relevant data are also collected here to allow for a discussion of electricity benchmarks. 3 Table 4 Approximate electricity consumption 2007 from the aluminium production chain in the EU27, calculated from data on production volume and specific electricity consumption; including activities not included in the EU ETS; excluding installations in Norway and Iceland (EEA, 2009) Activity Production Range of specific Approximate power volume power consumption consumption (Mt) (kWh/t product) (GWh) Alumina refining 6.8 225 - 260 1649 Pre-bake anode production 2.3 120 - 190 357 Primary smelting 3.054 14000 - 16000 1 45352 Primary casting 3.658 50 - 200 685 Secondary remelting 4.9 120 - 340 1127 Secondary refining 2.7 ? ?

INTRODUCTION Although a considerable number of precipitants have been pro- posed for the determination of aluminium, direct precipitation of aluminium hydroxide by means of ammonium hydroxide, fol- lowed by ignition to oxide, is most commonly used, especially if no separation from iron is desired, in which latter case special methods must be employed. While the general principles involved in this determination are extremely simple, it has long been recog- nized that certain precautions in the precipitation, washing, and ignition are necessary if accurate results are to be obtained. While, however, most of these details have been studied and dis- cussed by numerous authors, it is noteworthy that few publica- tions or textbooks have taken account of all the factors. In the 515 ; 516 Bulletin of the Bureau of Standards [Voi.i3 present paper it seems desirable, therefore, to assemble the various recommendations and to consider their basis and their accuracy.

  • 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.

  • The Adsorption Characteristics of Cu(II)
    www.nature.com/scientificreports OPEN The adsorption characteristics of Cu(II) and Zn(II) on the sediments at the mouth of a typical urban polluted river in Dianchi Lake: taking Xinhe as an example Xiang‑shu Ma1,2,3, Leng Liu1,2,3, Yi‑chuan Fang1,2,3 & Xiao‑long Sun1,2,3* This study is to determine the spatial distribution characteristics of Cu and Zn adsorption on the sediments of the estuary of Dianchi Lake, as well as the composite adsorption law of Cu and Zn on combinations of sediment organic matter, metal oxides, and organic–inorganic composites. The relationship between the adsorption contribution of each component of the substance. A static adsorption experiment was applied to the sediments in the estuary of Dianchi Lake. The relationship between adsorption capacity and sediment composition was analyzed through correlation analysis and redundant analysis. The results show that along the direction of the river fow and the vertical depth, the adsorption capacity presents a relatively obvious spatial distribution law; the change trend of sediment component content is not the same as the change trend of Cu and Zn adsorption capacity. The change trend of the sediment component content is not the same as the change trend of the adsorption amount of Cu and Zn, and the compound efect between the components afects the adsorption amount. The adsorption of Cu by the four groups of sediments after diferent treatments is more in line with the Freundlich isotherm adsorption model; When adsorbing Zn, the untreated and removed organic matter and iron‑aluminum oxide group are in good agreement with the Freundlich model, while the organic matter‑removed group and the iron‑aluminum oxide removal group are more consistent with the Langmuir isotherm adsorption model; The adsorption contribution rate of organic–inorganic composites in sediments is not a simple addition of organic matter and iron‑ aluminum oxides, but a more complex quantitative relationship.

  • 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.

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.

  • An Aluminium-Led Energy & Industry Renewal for Central Queensland
    1 Clark Butler, Guest Contributor September 2020 An Aluminium-Led Energy & Industry Renewal for Central Queensland A Case Study of Gladstone and Boyne Smelters in Queensland Executive Summary “The full emergence of Australia as an energy superpower of the low-carbon world economy would encompass large-scale early-stage processing of Australian iron, aluminium and other minerals.”1 Australia has the potential to become a much more significant economic power in a decarbonised world. The country’s renewable energy resources sit at the heart of this enormous economic opportunity. Australia could lead the world in producing the components of low-carbon industrialisation: aluminium, steel, cement, silicon, lithium and rare earth minerals, with value-adding Australia could lead the processing before exports to enhance Australian world in producing the investment and employment. components of low- This report explores how the country can both carbon industrialisation. decarbonise and grow heavy industry with a focus on Gladstone, Queensland. The generation of electricity is Australia’s largest source of carbon emissions (33%). Closing the country’s four aluminium smelters would reduce Australian electricity demand by 10% with a consequential reduction in emissions associated with electricity use. However, electricity is also key to the rapid decarbonisation of other major emitting sectors such as transport, heating, industrial processing and manufacturing that account for 55% of the country’s emissions. Instead of closing the country’s loss-making and high emitting aluminium smelters, these industries could transition rapidly to renewable electricity, invest in plant upgrades to support demand response management, and profit from the long-term growth of the metals and industrial processing markets.
