General Travancore Titanium Products Limited is currently producing TiO2, antase grade, through the sulphate route. Ilmenite, a mixed oxide of titanium, ferrous iron and ferric iron is the main raw material for the production of titanium dioxide pigment.  Ilmenite is reacted with sulfuric acid in reinforced cement concrete tanks called Digesters, lined with lead and acid resistant bricks.  Exothermic reaction is initiated by the heat of dilution of the acid with water and a porous cake is formed.  The mass in the solid form is dissolved in dilute sulphuric acid to get titanium  in solution as titanium oxy sulphate (TiOSO4) along with other metallic ingradients in ilmenite as their sulphate. The liqour is reduced using scrap iron, when the ferric iron gets completly reduced to the ferrous state.

News February 15, 2021 - A copperas recovery plant and a renovated sulphuric acid plant are the two new ones Chief Minister Pinarayi Vijayan on Monday inaugurated a copperas recovery plant and the renovated sulphuric acid plant at the Travancore Titanium Products Ltd (TTP) at Kochuveli.  The Chief Minister also kicked off the 75th anniversary celebrations of the company and inaugurated a guest house constructed as part of the anniversary.  The copperas recovery plant is capable of producing 165 tonnes of iron sulphate, or copperas, daily. This comes as a byproduct of titanium dioxide produced at TTP. “The recovery of copperas will help TTP to come out with iron sulfate as a value-added product. Additionally, the quality of titanium dioxide produced at TTP too will improve,” TTP managing director Georgee Ninan said.  The plant was constructed at a cost of ₹34 crore, including ₹15.5 crore sanctioned by the present LDF government. The copperas recovery plant would also help TTP cut down pollution, company officials said.  The sulphuric acid plant has been renovated at a cost of ₹10 crore. Established in 1995, the plant’s production capacity had eroded over the years.  TTP was incorporated on December 18, 1946, in collaboration with British Titan Products, UK. The company started production of Titanium Dioxide through sulphate Route in 1951.  Industries Minister E.P. Jayarajan presided. Mayor Arya Rajendran, former MLA Anathalavattam Anandan, TTP chairman A.A. Rasheed and managing director George Ninan were present.
