The Effect of Palm Char Properties on Malaysian Ilmenite Ores by Carbothermal Reduction [PDF]
Archives of Metallurgy and MaterialsTo identify the mineral grade ore, two distinct Malaysian ilmenite ores (FeTiO3) from different placers deposits were examined. The sources of ilmenite ore were the Kinta Valley in Perak and the Langkawi Black Sand Beach in Kedah.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Ilmenite electric arc furnaces (EAFs) are used for smelting titanium‐iron oxide ore at high temperatures generated by electrical arcs to produce titanium slag and pig iron. As these units are pushed to their limits, ensuring safe and reliable operation becomes challenging.

Preparation of TiO2 pigment from ilmenite ore concentrate by molten alkaline process
Vietnam Journal of Science, Technology and Engineering, 2023 TiO2 pigment production from an ilmenite concentrate via a molten alkaline process was investigated. The ilmenite concentrate (54.19% TiO2) was first roasted in the molten NaOH system at various temperatures ranging from 600 to 800°C while the mass ...

Geostandards and Geoanalytical Research, EarlyView.Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the
