Abstract

309,597. Deutsche Gasgl³hlicht Auer- Ges. April 14, 1928, [Convention date]. Sulphuric acid.-In the treatment of titanium ores containing chromium with sulphuric acid with recovery of the latter for re-use, the chromium is removed from the recovered acid by concentration thereof to at least 92 per cent strength, followed by prolonged heating at or above 300‹ C.
