Titanium Dioxide (TiO2) Production and

2010-3-15  Titanium Dioxide (TiO2) Production and Manufacturing Process. TiO2 is produced from either ilmenite, rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores.

Application Note Titanium Dioxide Sulfate Process
