Desulphurisation of Iron

Abstract

THE elimination of sulphur from iron and the chemical reactions, whereby sulphur, in the presence of powerful basic materials, is removed from crude iron, has recently attracted considerable attention. There are many reasons for this; pure ores have become comparatively scarce, and to some extent the same may be said of the fuel or coke used in the process of smelting. And even if this be not strictly applicable in all districts where the manufacture of iron is pursued, yet it cannot be gainsaid that excessive competition, with concurrent low prices, have had an influence in rendering the strictest economy in the manufacture absolutely necessary, and thus in a measure preventing the free use of pure high-priced materials.
