Titanium Dioxide Produce process 

Sulfuric acid main process: 

Acid hydrolysis, sedimentation, ferrous sulfate separation, hydrolysis, calcination, post-treatment (wet grinding, inorganic coating), Washing, drying, airflow crushing, organic coating, packing; second, chlorination (rutile titanium dioxide production only) main raw materials: high titanium slag (chlorinated slag), chlorine gas, oxygen, 

Chloride  main process:

Chlorination, refining, oxidation, Post-treatment (wet grinding, inorganic coating, washing, drying, airflow crushing, organic coating), packaging; third, hydrochloric acid method (capable of producing anatase, rutile titanium dioxide; nanometer titanium dioxide) main raw materials: titanium concentrate or acid soluble titanium slag, 

Main processes of hydrochloric acid: 

Leaching, reduction, ferrous separation, primary extraction, secondary extraction, calcination, post-treatment (wet grinding, inorganic coating, washing, drying, airflow crushing, organic coating), packaging.
