Experimental Investigations and Phase Relations in the Liquid FeTiO3-Ti2O3-TiO2 Slag System
Seim, Stian (Doktoravhandlinger ved NTNU, 1503-8181; 2011:105, Doctoral thesis, 2011) -
Organic binder as a substitute for bentonite in ilmenite pelletization
Sunde, Marius (Master thesis, 2012)TiZir Titanium & Iron produces high titania slag and high purity pig iron from ilmenite in Tyssedal. The ilmenite is pelletized before smelting. Bentonite is added to the ilmenite concentrate as a binder to give the pellets ... -
Phase Transitions and Microstructural Changes During Oxidation and Reduction of a Weathered Ilmenite Concentrate
Salehi, Hossein; Seim, Stian; Kolbeinsen, Leiv; Safarian, Jafar (Peer reviewed; Journal article, 2021)The present work aims to investigate the link between the oxidation and reduction of a weathered ilmenite concentrate in terms of phase transitions, microstructural changes, and element distribution. An ilmenite concentrate ... -
Reduction of Norwegian and Indian ilmenite with carbon monoxide and hydrogen gas blends
Lobo, Stephen Ceasar; Kolbeinsen, Leiv; Seim, Stian (Journal article, 2016)Synthesis gas, produced from natural gas, can be used to minimise coal consumption and carbon dioxide emissions during the processing of ilmenite. Two different ilmenite ores have been reduced with carbon monoxide and ... -
Slag Refining of Iron with Respect to Phosphorus
Saadieh, Raghed (Master thesis, 2014)TiZir Titanium and Iron produces high purity pig iron and titania slag from ilmenite. However, new ilmenite ores from Grande Côte Mineral Sands Project mine contain high level of phosphorus, which will contaminate the ... -
Solidification of Titanium Slags and Influence on Post Processing
Stana, Rune Hagberg (Master thesis, 2016)Ilmenite is a titanium-rich ore, and accounts for almost all the world's consumption of titanium bearing minerals. One of the main uses of titanium is as powdered TiO2, used extensively as whitening pigment. The first step ... -
Synthesis of ilmenite
Canaguier, Vincent Yves (Master thesis, 2014)Ilmenite ores are currently processed at TiZir Titanium & Iron AS in Tyssedal. To be prepared for a change in the raw material composition, the effect of the impurities in the ilmenite ores has to be investigated. It is ...
