• Raw Materials: Ilmenite ore (FeTiO3) or titanium slag.
• Acid Digestion: The ore is treated with concentrated sulfuric acid to dissolve titanium, forming titanium sulfate solution.
• Hydrolysis: The titanium sulfate solution is hydrolyzed under controlled conditions to precipitate hydrous titanium oxide (TiO2·nH2O).
• Washing & Filtering: The precipitate is thoroughly washed to remove impurities and then filtered.
• Calcination: The hydrous oxide is calcined at high temperatures (typically 800-1000°C) to convert it into the crystalline rutile form and drive off water. This step is critical for developing particle size and optical properties.
• Milling & Surface Treatment: The calcined product is finely milled to achieve desired particle size distribution and then undergoes surface treatment with inorganic compounds (e.g., alumina, silica) to improve dispersion, weatherability, and compatibility with papermaking additives.

Chloride Process Overview:

• Raw Materials: High-grade rutile ore or titanium slag.
• Chlorination: The raw material is reacted with chlorine gas and coke at high temperatures (around 1000°C) to produce titanium tetrachloride (TiCl4) in a fluid bed reactor.
• Purification: The TiCl4 is purified through fractional distillation to remove metallic chlorides.
• Oxidation: Purified TiCl4 is reacted with oxygen at high temperatures (around 1200-1400°C) to form fine rutile TiO2 particles and regenerate chlorine.
• Post-treatment: Similar to the sulfate process, the resulting titania tio2 undergoes milling and surface treatment to optimize its performance for specific applications like papermaking.

Testing Standards: Throughout both processes, rigorous testing according to international standards such as ISO 591-1:2000 (Titanium dioxide pigments for paints, varnishes and plastics – Part 1: Classification) ensures product consistency and quality. Each batch undergoes checks for parameters like TiO2 content, brightness, oil absorption, and particle size distribution. The careful control over these parameters ensures a long service life and consistent performance in target industries like papermaking, contributing to energy saving in processes and enhancing corrosion resistance in the final product's stability.
