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. New technologies are needed to utilize complex Ti ores, such as ilmenite, and reduce the carbon footprint of TiO2 extraction. Ammonium sulfate roasting has been revealed as an efficient …
The raw ores for ilmenite separation are usually tailings of iron beneficiation. With characteristics of TiO 2 grade of 6.46% and TFe grade of 12.34%, the early tailings of the Midi concentrating mill are investigated to recycle the valuable minerals. In the present study, the focus is on the ilmenite flotation separation process.
