Ilmenite (FeTiO3) and rutile (TiO2) are the only naturally occurring titanium bearing minerals that have been seriously considered as suitable feedstock for either the titanium metal producing or titanium pigment industries (Ismail et al., 1983). Ilmenite commonly occurs altered to mixtures of TiO2, FeO and Fe2O3, with the TiO2 content increasing from 49 …
Many of iron sand found in coastal Indonesia that contains some valuable minerals such as hematite (Fe2O3), ilmenite (FeTiO3) sand rutile (TiO2).

The results proved the feasibility of accurately sorting each individual iron ore based on its predicted TFe content using HSI. This methodology offers technical …
Reduction roasting-magnetic separation realizes the separation of titanium and iron in high-titanium beach titanomagnetite. However, the TiO 2 grade in titanium concentrate is low, and few studies have investigated low-titanium beach titanomagnetite.
The reason why the technique used to produce cast iron was lost is because the method to isolate iron sand changed from the traditional gravity separation method (Kanna-nagashi) to a modern magnetic separation method after the end of WWII, which resulted in a decreased content of TiO2.
TiO2 extraction was conducted using sulphate method, by reacting milled iron sand with sulfuric acid at high temperatures (>110°C) for ± 30 minutes. Titanium extract was then …
The SEM-EDS examination and chemical analysis indicated that the iron and titanium were segregated during the reduction of the iron sand concentrate pellet, especially during heating from 1000 to 1380 °C.
In this research, the purity level of TiO 2 from Lampung's iron sand has been tried to improve using the leaching method by variation of iron sand and NaOH ratio …
Abstract: In this study, we investigated the separation of iron and scandium from Sc-bearing red mud. The red mud object of our study contained 31.11% total iron (TFe), 0.0045% Sc, hematite (Fe2O3 ...
Approximately a third of the Earth's crust consists of iron, which the main ingredient used to make steel. In nature, it exists as an ore, and steel manufacturers must extract it before they can use it. One such ore is a type of iron oxide called titanomagnetite, which is formed as volcanic lava crystallizes. ...
Magnetic separation can remove iron and other magnetic minerals from ilmenite minerals. This method includes weak magnetic separation and strong magnetic separation. The weak magnetic separation is to separate titanomagnetite, while the strong magnetic separation is to discharge qualified tailings and prepare for the …

Since it had a high content of TiO2 (16.37 mass%) when isolated with a gravity separation method, it is clear that the Kusuri iron sand functioned to supplement the amount of TiO2 present and facilitate cast iron production from low TiO2-containing iron sand.
Iron sand collected with traditional gravity separation method contained 8 to 12% TiO 2, while iron sand collected with modern magnetic separation method contained less than 5% TiO 2. When gravity-separated iron sand was used in a tatara under strong reducing conditions, zuku (cast iron) flowed out of the tatara.
