The total cost of the fertilizer project, from mining to production, is estimated at U.S. $1.9 billion; and the aluminum project, at $4.4 billion. Both are dependent on the construction of a $2 billion rail link from the phosphate and bauxite mines. The Ras Al-Zour site, about 40 miles north of the Industrial City of Jubail, is likely to attract additional investment, with a huge potential for downstream industries, and for the processing of other minerals such as silica, magnesite, dolomite and calcium carbonates.
