Fast Determination of Fe~(2+)/Fe~(3+) Ratio in Ilmenite

摘要

Ilmenite (FeTiO_3) is an initial raw material in titanium white manufacture. The Fe~(2+)/Fe~(3+) ratio in ilmenite is measured before the sulphate technological process is started. The possibility of fast measurements of this ratio could help to control the manufacture process. A single-purpose Moessbauer effect analyser for the fast determination of Fe~(2+)/Fe~(3+) ratio in ilmenite was built. The fast algorithm based on the calculation of a Fe~(2+)/Fe~(3+) ratio from heights of spectral lines allowed to reduce the time of one analysis to ten minutes.
