Book edition hematite rutile and ulvöspinel separating from ilmenite Fe Cu and Ag containing sulfides are developing crystal Thus oxides such as chromite ilmenite and magnetite plus PGE alloys separate from examples are for instance surplus Fe or Ti in ilmenite or extra Fe in Cu sulfides such as oriented exsolution lamellae of rutile
·The ilmenite concentrate was provided by the Panzhihua Iron and Steel Group Corporation Sichuan China The as received ilmenite was sieved; only particles in the 100 120 mesh range were used during the ilmenite primarily contained hexagonal FeTiO 3 as illustrated by the XRD pattern in Fig chemical composition of the ilmenite is
·Here we investigate one of the youngest known bodies in the Rogaland Igneous Province the Tellnes ore body an ilmenite rich norite currently mined for its ilmenite content which intrudes the Åna Sira anorthosite The Tellnes is dated some 12 Myr younger than the initial anorthosite intrusions Schärer et al 1996 In addition we report
The world s largest open cast ilmenite mine is the Tellnes mine located in Sokndal Norway and run by Titania AS owned by Kronos Worldwide Inc a hard rock ilmenite mine which produces most of Norway s 380 000t of ilmenite production In Karhujupukka located in Kolari northern Finland there is a magnetite ilmenite ore at around 5 million
·The present study investigated the oxidation of ilmenite from Tellnes Norway at 700°C in air and compared the leaching ability of pre heated and non heated Tellnes ilmenite in 20% HCl solution
·The Tellnes open pit mine is located within the Precambrian Egersund province in Southwestern Norway Titania A/S has been operating the mine since 1960 In the orebody about one third of the rock consists of ilmenite FeTi03 In recent years the total mined material has been about 8 million tonnes/year and the ore production
Abstract The Rogaland anorthosite province S Norway contains numerous Fe Ti oxide deposits including the second most important ilmenite deposit in the world the Tellnes deposit The largest deposits are located in the Åna Sira anorthosite massif Others occur in the Håland Helleren anorthosite massif particularly along the deformed contact with the Egersund Ogna massif
·1 Introduction Ilmenite and rutile are the main sources of titanium with 90% of commercial TiO 2 coming from ilmenite and 10% from rutile Hard rock deposits associated with Proterozoic anorthosites provide 30% of ilmenite while the remaining 70% and all rutile comes from placers Gambogi 2010 Despite an abundance of world resource for Ti ores the
The ilmenite deposit Tellnes south Norway is a through like massive ore body of ilmenite norite with sharp borders against the surrounding anorthosite Samples taken from drill cores are preferably used for detailed mineragraphic description paragenesis and
Tellnes Mines Sokndal Rogaland Norway Field of View 2 mm The microstructure of high grade titanium ore from Tellnes mines Typical granular ilmenite aggregate light grey to dark brown grey rotation tints in association with pyrite isotropic and chalcopyrite pale green rotation tints in norite host rock various internal reflections

·The present study investigated the oxidation of ilmenite from Tellnes Norway at 700°C in air and compared the leaching ability of pre heated and non heated Tellnes ilmenite in 20% HCl solution
·influence on ilmenite composition is also examined Finally new light is shed on the age of the Tellnes ilmenite deposit which hitherto has been believed to be 10 Ma younger than other plutons of the Rogaland Anorthosite Province Scha¨rer et al 1996 Geological background The Tellnes ilmenite deposit belongs to the Rogaland
·world class Tellnes ilmenite deposit part of the late Proterozoic 930 920 Ma AMC series of the Rogaland Anorthosite Province SW Norway More than 100 samples from drill cores reveal significant petrographical and compositional variations within the ore body Four zones are defined based on variations in modal proportions and cumulus
The Tellnes deposit is an ilmenite rich norite intrusion into the Åna Sira anorthosite as evidenced by sharp contacts numerous apophyses cutting the surrounding anorthosite intrusive breccias and xenoliths of anorthosites It has a sickle shaped outcrop more than 2700 m long and is more than 400m wide in its central part The northwestern
The high grade Tellnes ilmenite mine where ilmenite is the main ore mineral and is easy to extract is not representative of the other Ti deposits in Europe or even the rest of the world The global reserves of Ti rich oxide minerals such as ilmenite FeTiO3 and rutile TiO2 are about 62 and 880 million tonnes respectively while the global
·The Tellnes ilmenite deposit belongs to the late Proterozoic Rogaland Anorthosite Province see Duchesne 2001 for a review emplaced in the south western part of the Sveconorwegian orogenic belt SW Norway Fig 1 The Province comprises different units of the AMC series four large massif type anorthosite plutons Egersund Ogna Håland Helleren
·Compared with ilmenite of the Tellnes Fe Ti oxide deposit in Norway the ilmenite in the Panzhihua intrusion is high in MgO and FeO very high in TiO2 and MnO but very low in Fe2O3 suggesting that the ilmenite formed in mantle plume environment is
·Tellnes ilmenite is an important feedstock for the production of high grade titanium pigment The present study investigated the oxidation of ilmenite from Tellnes Norway at 700 °C in air and compared the leaching ability of pre heated and non heated Tellnes ilmenite in 20% HCl solution at 160 °C Through the heat treatment ilmenite FeTiO 3 is oxidized to
·The mineralogy and textural relationships of the Tellnes ilmenite concentrate were determined to evaluate the effect of mineralogical characteristics of the raw material on sulphate route TiO2 pigment production It was found that the presence of hematite exsolutions and their grain size twinning the amount of ferric iron in the ilmenite and the grain size
·The mineralogy and textural relationships of the Tellnes ilmenite concentrate were determined to evaluate the effect of mineralogical characteristics of the raw material on sulphate route TiO2 pigment production It was found that the presence of hematite exsolutions and their grain size twinning the amount of ferric iron in the ilmenite and the grain size
The ilmenite norite of the Tellnes Fe Ti deposit in the Aana Sira massif type anorthosite is connected to a main dike which varies in composition from monzonorite to quartz mangerite Fine grained satellite dikes also occur in the vicinity of the main number of rock samples have been analyzed for 36 major and trace elements An Rb Sr
·Fe Ti oxide ores in the Proterozoic Suwalki massif type anorthosite northeastern Poland have been recognized through geophysical exploration and extensive drilling down to 2 600 m depth The Fe Ti oxide rich rocks from Suwalki consist of vanadium poor Ti magnetite in lenses varying from the centimeter to the kilometer scale Fe Ti‐rich rocks are commonly
·Despite some popular misconceptions titanium is not a rare or an exotic element; in fact it is the ninth most abundant element on earth s crust with an average abundance estimated between % and % wt [1] [2] Because of its strong affinity with oxygen titanium s most common minerals are oxides [3] These minerals Fig include ilmenite FeTiO 3
