=Spain.=--Spain is rich in iron-ore reserves, but the iron and steel manufacturing industry has had little development. The annual production of iron ore in Spain during the last years before the war amounted to about 9,000,000 tons, of which more than 8,000,000 tons were exported. The consumption of iron ore by Spanish blast furnaces has been in the neighborhood of 800,000 tons annually. The principal iron ores of Spain lie in the northwestern part, in the provinces of Viscaya, Oviedo, Lugo, and Santander; in the northeastern part, in the provinces of Teruel and Guadalajara; and in the southeastern part, in the provinces of Granada, Almeria, Murcia, Sevilla, and Huelva. The iron ores of the Bilbao district of Viscaya are all of Bessemer grade, and for many years large amounts have been exported to England for use in Bessemer plants to supplement ores from the Cleveland and other districts of England. Because of their excellence, they have been in continuous demand, and the English iron and steel industry has depended to a considerable extent upon these and other high-grade ores of Spain. In more recent years, Germany has also become interested in the Bilbao iron fields, and in the last years before the war Germany took more than one-third of the total Spanish production, including large amounts of ore from southern Spain as well. Spanish interests own important deposits in southeastern Spain and in the Bilbao district. Most of the ore of southeastern Spain is of high grade, being rich in iron and low in phosphorus. Nearly all of it is of Bessemer quality, and some is very low in phosphorus; the latter is exported extensively for use in the manufacture of low-phosphorus pig iron. The United States has been largely dependent in past years upon Spain for this grade of ore, more than 100,000 tons being imported annually. Spain has a number of blast furnaces and steel plants, the principal ones being at Bilbao, in the Province of Viscaya. More than 300,000 tons of pig iron are produced annually in Viscaya, this being approximately three-fourths of the total output of pig iron in Spain. =European Russia.=--In European Russia[37] the principal deposits of iron ore are distributed over four chief districts: Ural Mountains, central Russia, southern Russia and the Caucasus.
