Rock Ilmenite Processing
Towards sustainable TiO2 production: An investigation of environmental
Australia has one of the largest resources of ilmenite and rutile forms of titanium oxide and it is quite expected that Australia is facing the environmental impacts and health effects caused by the titanium-ore extraction process (Haque et al., 2014, Jones, 2009, Reichl et al., 2016).The effect of this processing route on human health and ecosystems needs to be …
