On the other hand, the ,waste, waters in the ,titanium, dioxide preparation and also those which are obtained in the ,waste acid, recovery, cannot as a rule be completely accommodated in the process. They contain relatively few components, e.g. 11 g sulfuric ,acid,, 67 mg iron, and 1.2 mg chromium per liter.

11 Depending on the production process or the are used, titanium waste may include one or more of the following: dilute sulfuric acid (strong and weak acid waste), red sludge (copperas or ferrous sulfate), solid residue (chloride or sulfate salts), are and pigment

The processing of ,titanium, metal occurs in four major steps: reduction of ,titanium ore, into "sponge", a porous form; melting of sponge, or sponge plus a master alloy to form an ingot; primary fabrication, where an ingot is converted into general mill products such as billet, bar, plate, sheet, strip, and tube; and secondary fabrication of finished shapes from mill products.

In this research, a potentially more ecofriendly chemical pathway for TiO2 production from concentrated titanium ore, aka titania slag, is presented. The new method consists of three critical steps including transformation of the titania slag to a lower-valence titanium suboxide by aluminothermic reduction, digestion by using mild acid, and controlled hydrolysis accompanied by acid recycling.
