Chlorination process choice depends on the TiO2 content in raw material. Many western countries to natural rutile (95% ~ 98%TiO2) and high-grade artificial rutile as raw material, the process is simple, chloride, low material consumption, high utilization rate of chlorine and simple equipment system.
China titanium slag as raw material, the content of impurity, high material consumption, low utilization rate of chlorine, equipment system is huge. Titanium sponge production early, some factory used shaft EAF process.
