Abstract
ALREADY in the pre-war years the supplies of high-class haematite to the iron-smelting districts of Europe trom the nearer sources were getting short, and the time was in sight when, for iron ores low in phosphorus such as are required for the production of the “haematite grade” of pig-iron demanded by those, who make steel by the “acid” process, we shall have either to turn our attention to sources of supply which are less readily accessible, or so to improve metallurgical processes that, from ores which are abundant in closer proximity to the coal held, trustworthy substitutes for “Bessemer-grade” acid steels can be economically produced. The thesis advanced by the author of these Howard lectures is that, notwithstanding that the low-grade phosphoric ores of the Englisn Jurassic rocks yield a pig-iron which for steel-making requires refining upon a basic hearth, in Britain the second of the two alternatives mentioned should be chosen.
