Abstract: | |
The South Rogaland igneous complex with its large anorthositic, noritic and mangeritic intrusions hosts a number of Ti-Fe deposits. 81 prospects and mines are known, 35 being situated within the Åna-Sira anorthosite massif. Blåfjell mine, active from 1863-1876, produced some 90,000 t of ore. Storgangen (1916-1965) yielded a total of 10 Mt with another 60 Mt of proven reserves. The only operating mine today is Tellnes, which started production in 1960. In 1984 about 2.6 Mt of crude ore were mined, equivalent to 656,000 t ilmenite concentrate and accounting for 10% of the world production of TiO2. By-products were 17,000 t magnetite concentrate and 9,000 t sulfide concentrate. Proven ore reserves are 300 Mt. |
