Decomposing the Titaniferous Magnetite Concentrate with Hydrochloric Acid

The decomposition of TMC with hydrochloric acid solutions (15–25% HCl) at the boiling point of the reaction mixture and atmospheric pressure has been investigated. The processing conditions have been determined for efficient recovery of titanium (up to 99.3%) as photocatalytically active anatase and...

Description
Summary:The decomposition of TMC with hydrochloric acid solutions (15–25% HCl) at the boiling point of the reaction mixture and atmospheric pressure has been investigated. The processing conditions have been determined for efficient recovery of titanium (up to 99.3%) as photocatalytically active anatase and for extracting Fe (up to 99.6%) and V (98.8%) into the leaching solution. Subsequent treatment of the leach liquor with aqueous ammonia affords 99.3 wt % Fe 2 O 3 and an iron-vanadium product containing 3.2 wt % V 2 O 5 .
