The major impact categories are climate change, human health (cancer), human health (non-cancer), ecotoxicity, and eutrophication. The analysis results show that the highest impact is caused in climate change, at 0.295 kg CO 2 eq, which is due to the large amount of electricity consumption in the ilmenite extraction process. Then, …
Currently, it is difficult to obtain high-purity titanium from ilmenite to produce titanium dioxide (TiO2). More severely, it causes serious environmental pollution.
