Medium Term--Capacity and Industry Structure

摘要

Table 6 shows that at the end of 2006 world primary aluminium smelter capacity was 37.89 million t/y at 257 identified plants. Of the world total 7.4m t/y was the older Soderberg anode technology, a proportion that is steadily falling as Soderberg smelters are closed or converted to prebaked anode technology. Table 7 lists all committed changes to primary smelter capacity. By 2010 these projects will add 4.3 million tonnes (net) to world capacity, of which 1.8m tonnes is in 2007. Since the last report no major projects have been added to the list of committed projects.
