South Africa Titanium Mining Industry: Titanium Ore ...

Titanium ore always involved in ilmenite and miners need to process the ilmenite to get high grade titanium materials in South Africa. Ilmenite nominally contains only 53% TiO2, so it must be purified before further processing. Raw ilmenite or slag ore is first soaked in sulfuric acid for several hours to free up the titanium from the mineral.
