Toward Decarbonization of the Titanium Industry via Hydrogen Plasma Smelting Reduction. [PDF]
Adv Sci (Weinh)Hydrogen plasma smelting reduction enables direct, zero‐carbon conversion of low‐grade ilmenite into steel‐grade iron and a titania‐rich precursor for pigment production. The single‐step process merges smelting and refining, sharply lowers silica content, and offers a breakthrough path for sustainable, high‐value extraction from abundant mineral sands.

Methods of Extracting TiO2 and Other Related Compounds from Ilmenite
Minerals, 2023 Although ilmenite and rutile are extensively used to extract TiO2 at the industrial level, through the sulphate and chloride processes, they can also be recognized to possess the potential to be employed as the raw material to synthesize other titanium ...

The Recovery of TiO2 from Ilmenite Ore by Ammonium Sulfate Roasting–Leaching Process
Processes, 2023 TiO2 production is a key part of Ti metallurgy and Ti recycling, and the process itself has turned out to be energy-consuming and material-consuming.

WinMIgob: A Windows program for magnetite-ilmenite geothermometer and oxygen barometer
Journal of Geosciences, 2021 A Microsoft ® Visual Basic software, called WinMIgob, has been developed for wet-chemical and electron-microprobe compositions of coexisting magnetite–ulvöspinel and ilmenite–hematite solid solutions to calculate the temperature ( T , °C) and oxygen ...
