Apr 01, 1975· BENEFICIATION OF ILMENITE ORES . United States Patent 3875286 . Abstract: An ilmenite ore may be beneficiated by converting the ore into a pseudobrookite-containing material, reducing that material to give a product having at least 4% of its iron content in the ferric state, and finally leaching the reduced product. If a hydrochloric acid

success. As previously indicated, hydrochloric acid leaching of ilmenite was not new but Austpac developed some effective in-house techniques to significantly reduce costs compared with other systems. The most important of these was the use of atmospheric pressure leaching and the patented ‘Enhanced Acid Regeneration’ (EARS) process (5).
