· The Kroll has been employed for extraction since the 1950s. It is a labour and energy intensive multi-step semi-batch . The post-extraction processes for making the raw into alloys and products are also excessive, including multiple remelting steps. Invented in the late 1990s, the Fray-Farthing-Chen FFC Cambridge extracts from solid oxides at

In this research, a potentially more ecofriendly pathway for TiO 2 production from concentrated , aka titania slag, is presented. The new method consists of three critical steps including transformation of the titania slag to a lower-valence suboxide by aluminothermic reduction, digestion by using mild acid, and
