Titanium slag is one of the main feedstock types for TiO2 manufacture. Ilmenite is converted to titanium-rich materials using a high temperature metallurgy process. The 90% and the 78% titanium slag produced is used in the chloride and sulphate TiO2 manufacturing processes respectively. Having a readily available source of titanium slag is crucial for a TiO2 manufacturer, and by having the ability to produce it internally, Henan Billions will have greater security of ore supply and more control of its raw material costs. In addition, the process has valuable by-products such as reduced ilmenite and pig iron, which are used as raw materials for the electric welding and special steel industry. Reduced ilmenite is also used in the sulphate TiO2 manufacturing process.
The titanium slag project started in early 2013. Construction was completed in mid-2014 and started to operate in September of the same year. Until March 2015 over 20,000 tonnes of qualified titanium slag has been produced, as well as 14,000 tonnes of reduced ilmenite. Henan Billions has received a positive response from users of both titanium slag and reduced ilmenite.
With its development of chloride process TiO2 production and its flexibility and stability of feedstock supply, Henan Billions is rapidly growing to become an even more significant player in the global titanium dioxide market.
