Layers of apatite magnetite and ilmenite-rich gabbro also occur in the Sept Iles intrusion in Quebec (Namur et al 2010 2012) Other ilmenite-rich deposits may be essentially massive oxides (e g the Big Island massive hemo-ilmenite dike that crosscuts the Allard Lake anorthosite) and their origins are controversial (see below) Contacts in Sorel Tracy Province of Quebec Canada ramped up from 250 000t up to about 1 100 000t The titania-rich slag with 80 mass percent TiO 2 is produced by the continuous smelting of hemo-ilmenite ore with anthra-citecoalinanelectricarcfurnace(EAF) Thehardrockhemo-ilmeniteore is mined from the anorthositic Lac Tio deposit Allard Lake Quebec

Rob Hargraves worked on hemo-ilmenites from the Allard Lake area Quebec for his Ph D thesis in 1959 and returned with great interest to these samples in relation to the concept of lamellar magnetism Because the hemo-ilmenite ores produce large negative magnetic anomalies that can only be modeled with a significant remanent component they are good


Origin of the giant Allard Lake ilmenite ore deposit

1 Introduction An ilmenite deposit (50 67N 63 67W) was discovered in June 1946 in the Allard Lake area near a small lake named Lac Tio during the first aeromagnetic survey for ore exploration (Bourret 1949) It is located 43 km northeast of Havre-Saint-Pierre in Quebec

08/02/2012^^ en fait le titane oxyd ferrifre est de l'Ilmnite Et pour simplifier l'ilmnite est aussi le nom d'un groupe de minraux Le nom Ilmnite vient du nom du mont Ilmen en Russie o il a t dcouvert J'ai trouv qu'il y en aurait dans ta rgion entre autre au Allard Lake et Mont Saint-Hilaire au Qubec

Apart from prospecting in the field (ilmenite is a black very dense mineral) prospectors and geologists will need to use geophysical methods such as magnetic and gravimetric surveys and lake-bottom sediment or stream-sediment heavy mineral geochemistry to outline areas to be investigated Though it is still expensive a detailed gravimetric
