• Recovery of titanium from the leach liquors of

    01/03/1999· The leach liquor contained approximately 5 g l−1 titanium, 1 g l −1 vanadium, and 55 g l −1 iron in 75 g l −1 sulphuric acid. The objective was to achieve the maximum possible titanium recovery with maximum rejection of iron and vanadium. The organic phase comprised 10 vol.% tri- n-octylphosphine oxide (TOPO) in an aliphatic diluent.

    01/03/1999· A continuous counter-current SX mini-plant campaign to recover titanium from the leach liquor of a titaniferous magnetite has been evaluated. An average of 80% titanium (best value of 88% achieved) was recovered from a leach liquor containing approximately 50 g l −1 iron, 5 g l −1 titanium, and 1 g l −1 vanadium in 80 g l −1 H 2 SO 4,using an organic phase comprising 10 vol.% TOPO in

    01/04/2004· A reductive leaching process is proposed taking advantages of the recent advances in HCl regeneration from spent leach liquor. The different leaching parameters were optimised to obtain as little iron as possible in the titanium dioxide product. Synthetic rutile of about 90% TiO 2 and 0.8% Fe 2 O 3 was obtained from an Egyptian medium-grade ilmenite ore of grain size 100%–75 μm using 20%

  • US4158041A Separation of ilmenite and rutile Google

    This invention relates to a process for separating rutile and ilmenite from ilmenite leach tails and is effected by treating the leach tails from an acidic leach to a flotation step whereby gangue is separated from the unreacted ilmenite and rutile. The latter is then roasted at an elevated temperature in a hydrous atmosphere to convert the ilmenite to a magnetic material.

  • The Austpac ERMS and EARS Processes for the manufacture of

    Ilmenite ore is roasted at temperatures in the range of 800°C to 1,000°C to selectively magnetise the ilmenite fraction so that gangue minerals may be easily removed. Roasting also enhances the subsequent leaching operation by activation of the iron component of the ilmenite whilst at the same time rendering the titania fraction insoluble. Iron and other impurities are removed by leaching at
