Raw materials are shipped in from all over the world to supply Qatalum and unloaded at a dedicated berth near the smelter. An aluminium smelter the size of Qatalum, developed by the local Qatar Petroleum and its joint venture partner Hydro of Norway at Mesaieed in Qatar, has huge raw materials requirements. An immense logistics network is needed to ensure ingredients of the right quantity and quality are available on site at the right time. The main raw material required is aluminium oxide, or alumina. Alumina is refined bauxite, and four tonnes of bauxite are needed to produce two tonnes of alumina, which in turn make one tonne of aluminium. The Qatalum smelter will consume 1. The alumina is sourced under long-term agreements from refineries in Brazil and in Western Australia, in regular shipments of about 42, tonnes each. Some of the alumina is supplied by Hydro itself, as it owns stakes in alumina refineries in Brazil. Its alumina output was increased to 6. Hydro also owns a 20 per cent stake in a planned new refinery with Brazilian mining company Vale and Dubai Aluminium Dubal , which will have an initial capacity of 1. Vale is the majority shareholder with a 61 per cent stake, and Dubal owns the remainder. Once the alumina arrives in Mesaieed, it is transported from the dock to storage silos by a metre conveyer belt. Alumina is kept in two silos, each able to hold 65, tonnes. A minimum supply of 52, tonnes — enough for two weeks of production — is kept on site in case of disruptions to delivery schedules. Another essential raw material, petroleum coke, is also transported via the conveyor. Each year, Qatalum will require , tonnes of coke. This is stored in three smaller silos, each with a capacity of 25, tonnes. Coke is used, along with coal tar pitch, to make anodes that are used in the electrolysis process whereby pure aluminium is extracted from the alumina. The coke and pitch are imported under short-term contracts from India, China and Kuwait. The first 3,tonne consignment of pitch arrived at the end of October in a specialist vessel that keeps the tar at a constant degrees Celsius. At the port, the pitch is pumped into heated tanks, a process that takes up to 12 hours. The Qatalum smelter requires about 50, tonnes of pitch a year. The other raw material requirements are much smaller, but they also come from far and wide. There is one raw material vital to aluminium production that Qatalum is able to source locally, and that is gas. Electricity typically accounts for 27 per cent of the cost of producing aluminium, with alumina only slightly higher at 29 per cent. Subscribe or upgrade your current MEED.
