Approximately 300 titanium and iron-titanium mineral occurrences and deposits are known in Norway. The most significant deposits are:
- The Tellnes ilmenite deposit (in operation)***
- The Engebøfjellet rutile/garnet/eclogite deposit in the Sunnfjord region of western Norway (in operation)
- The Storgangen deposit (abandoned)
- The Bjerkreim P-Ti-V deposit in the Rogaland Anorthosite province in southernmost Norway

- Rutile-bearing scapolitized metagabbro exploited for apatite at Ødegården between 1872 and 1918 in the rutile-bearing scapolite- hornblende-apatite rock (Ødegårdite).
- Mine in operation since 1960, operated by Titania AS (Kronos Worldwide Inc.). The yearly mine production is about 500.000 t ilmenite concentrate with 44-45 % TiO2.
- The Storegangen mine, abandoned since 1964 after producing 10 Mt of ilmenite ore, still contains 60 Mt of demonstrated remaining resources.
- Recent studies and extensive drilling by Norge Mineraler have reported an indicated and inferred mineral resource of 1.55 billion tonnes, made up of consistent grades of vanadium-bearing magnetite, titanium-containing ilmenite and phosphate-rich apatite.
- The Husebø rutile-bearing eclogite deposit consists of variably eclogitised jotunite affected by retrograde alteration, with 3-5 % TiO2 outcropping more than 100.000 m2.
- Two types of Ti deposit occur in the Sunnfjord region: magmatic ilmenite-titanomagnetite deposits associated with Palaeoproterozoic mafic intrusions, and rutile-bearing Caledonian eclogitic rocks. The ilmenite deposits in the region are of minor economic interest, while the rutile-bearing eclogites represent a major mineral resource, particularly the Engebøfjellet deposit, today mined by Nordic Mining.
- The Rødsand deposit (in operation from 1899 to 1981) is disseminated to semi-massive Fe-Ti oxides within amphibolite. The crude ore produced contained 25-30 % magnetite, 3.5-4 % ilmenite and 0.15-0.20 % V. The magnetite concentrate contained 64% Fe, 2 % TiO2 and 0.7 % V2O3, and was the raw material for production of pig iron and ferrovanadium.
- Massive and disseminated Fe-Ti deposits occur in gabbros and anorthosites. Selvåg is the only deposit considered to be of potential economic interest in the Vesterålen-Lofoten region, with 44 Mt probable ore with 20-30 % titanomagnetite (0.6 % V2O3) and minor ilmenite.
- The larvikite-lardalite complex in the southernmost parts of the Permian Oslo Rift hosts a number of titanomagnetite-ilmenite-apatite occurrences of which the Kodal deposit was investigated for apatite in the 1970’s and 80’s, and the deposit has recently been evaluated by Kodal Minerals. The mineral resource is c. 50 Mt with c. 5 % P2O5 (12 % apatite), 25-40 % titanomagnetite and 5-10 % ilmenite.
