Roasting process. Ilmenite, as mined, has a high Cr 2 O 3 content which makes is unsuitable for direct smelting to titania slag. Some of this Cr 2 O 3 is removed at the mine when the ilmenite is passed through a magnetic separation step in which the highly susceptible Cr 2 O 3-rich fraction of the ilmenite is removed. The remaining minerals containing Cr 2 O 3 are not readily separable from ...

Sulfation Leaching Treatment ilmenite Concentrate …

Sulfate process plants, which produce less than 30 pct of the TiO2, are based on the dissolution of ilmenite and/or titanium slag in sulfuric acid. Iron sulfate is separated by crystallization, and the remaining solution is diluted to precipitated hydrated TiO2, which is calcined to TiO2. Chloride process technology, which is environmentally cleaner and generates less waste materials than the ...

Process Economics Program Report No. 117 TITANIUM DIOXIDE PIGMENT Titanium dioxide pigment can be produced by either a sulfate or a chloride process. The sulfate process is older, is better developed, and conventionally has used a low cost raw material, ilmenite. It does, how- ever, require more labor and capital and it produces large volumes of waste sulfuric acid. The chloride process …

by the sulfuric acid process [7]. The slag was treated in the same way as ilmenite with the exception that no separation of ferrous sulfate was necessary because the bulk of iron was already separated by reduction in the earlier step (Figure 13). The sulfuric acid treatment process of the slag, however, still suffered from the disposal problem of the waste acid and as a result it was abandoned ...
