Primary aluminium is aluminium tapped from electrolytic cells or pots during the electrolytic reduction of metallurgical alumina (aluminium oxide). It thus excludes alloying additives and recycled aluminium.
Primary aluminium production is defined as the quantity of primary aluminium produced in a defined period. It is the quantity of molten or liquid metal tapped from the pots and that is weighed before transfer to a holding furnace or before further processing.
Source of Data
The data included in this IAI Statistical Report have been derived from voluntary reports of IAI Member and non-Member companies. It also includes estimates of unreported production, providing a figure as close as possible to total global, annual production. These estimates are based on known, non-reporting ROW facilities. An estimate for China’s production is based on information available from a number of analysts, including Aladdiny, Beijing Antaike Information Development Co. Ltd, China Nonferrous Metals Industry Association (CNIA) and CRU Group.
The IAI Statistical System is designed to meet the requirement that, in general, individual company data be included only within appropriately aggregated totals by declared geographical areas and not be reported separately. The declared geographical areas and the primary aluminium producing countries which fall in those areas are detailed above.
One asterisk * indicates that the number is revised from previous publication. Two asterisks ** indicates that primary aluminium production data were not reported to the IAI by the company or companies producing primary aluminium solely within that country; these constitute “Estimated Unreported”, where data is available. Dates given against a country indicate that data were reported or not reported, as appropriate, for the limited period shown.
The IAI considers the figures shown to be reliable, but they may be subject to revision.
