Process

Titanium dioxide is manufactured by the sulphate process from ilmenite.Ilmenite , which is a mixture of Titanium dioxide and iron oxide, is reacted with sulphuric acid and disintegrrated into ionic state in solution. The titanyl sulphate on hydrolysis gives hydrated titanium dioxide, On calcination at elevated temprature the hydrated titanium dioxide is transformed into crystalline form. Both Anatase and Rutile grades aremanufactured by the same process varying the nucleating agents for crystal formation. The milled pigment is packed in 25kg HDPE bags for despatch.
