Ulvoespinel and its significance in titaniferous iron ores

Abstract

Discusses modes of occurrence, properties, and methods of identifying ulvoespinel, which is intimately associated with magnetite in samples of titaniferous iron ores from numerous localities. Ulvoespinel, composed essentially of Fe 2 TiO 4 , is strongly magnetic, and its presence in ores can materially reduce the amount of titanium recovered by magnetic methods of separating magnetite and ilmenite.
