[27] Partly estimated. [28] Largely estimated. More than two-fifths of the total annual output of iron ore in the world has come from the United States, and of the American production more than 80 per cent. is generally produced in the Lake Superior district. This district is, therefore, by far the most important iron-ore district in the world, producing annually more than 30 per cent. of the world’s total of iron ore. Germany and France have been next in importance to the United States as iron ore-producing countries, about 80 per cent. of the ore mined in these two countries being obtained from the Lorraine iron fields situated on the border. The annual output of these fields, which includes also the ores of Luxemburg, has been about 25 per cent. of the world’s production. The Lorraine district and the Lake Superior district together, therefore, produce somewhat more than one-half of the total iron ore annually mined in the world. The iron ore produced in Great Britain is obtained mainly from the Cleveland district of northern England, this district furnishing about 40 per cent. of the British total, equivalent to about 2.6 per cent. of the world’s annual production. In comparison, the Birmingham district of Alabama and the Krivoi-Rog district of southern Russia, which are next in importance to the Lorraine and Lake Superior districts, furnish about 3.5 per cent. and 3.2 per cent., respectively, of the world’s annual production.
