A $10.8bn joint venture between Alcoa and Saudi Arabian Mining has awarded contracts for the construction of an integrated aluminium complex at Ras Azzour, Saudi Arabia.

US-based Fluor Corp and WorleyParsons have won contracts for the supervision, engineering and procurements for the complex’s alumina refinery to be completed by December 2014.

Fluor will also complete the construction of the plant’s rolling mill while Fluor Arabia has been contracted for the management of services at the complex and engineering works and supervision of infrastructure at the site.

Swiss-based ABB has been awarded the contract to deliver electric power to the aluminium smelter.

The joint venture between Alcoa and Saudi Mining provides for a 1.8 million ton-per-year refinery, a 740,000 ton-per-year smelter, a bauxite mine with an annual capacity of four million tons and a rolling mill with a capacity of up to 460,000t.
