RECENT ACHIEVEMENTS IN PREPARING TECHNOLOGY OF SYNTHETIC RUTILE

An outline of synthetic rutile production is given. The recent achievements in preparing of synthetic rutile are reviewed. These achievements include some improvements on existing processes and new processes. The existing processes contain reduction-rusting process and week reduction-hydrochloric acid pressure leaching process. The improved processes contain improved reduction-rusting process, week reduction-hydrochloric acid fluid bed leaching process and week oxidization-hydrochloric acid pressure leaching process. The new processes contain one step chlorination process and titania slag-hydrochloric acid pressure leaching process.
