Old ilmenite mine. A about 4km long and up to 50m wide noritic orebody embedded in the Åna-Sira anorthosite massif. It was mined by Titania from 1916 to 1964. The total production was about 10 millions tonn ore with an average of 18-19 % TiO2, accounting for 11-13% of the world production of TiO2 during that period.
