titanium oxide factories

Lithopone or sulphide of zinc white has been in general use for twenty years or more in many industries where a white pigment of considerable body or hiding power is required that is not subject to change like lead carbonate and has not the brittle character of zinc oxide, besides being sold at a lower figure than either of these. Nevertheless it is still comparatively new to the general painting trade. Because of our tariff protection its manufacture in this country has made great progress. Yet in spite of this and the duty imposed on it, the imports are still in excess of the quantity manufactured here. A short history of its origin will no doubt prove of interest to our readers.

To address these challenges, researchers are exploring alternative production methods that are more energy-efficient and environmentally friendly. For example, the use of solar energy to power the oxidation of titanium ore has been proposed as a way to reduce the energy consumption of the sulfate process. Other approaches include the development of new catalysts that can replace sulfuric acid in the oxidation step, as well as the exploration of bio-based feedstocks for TiO2 production.
