This invention relates to a process for beneficiating a titaniferous ore. The process comprises calcining the titaniferous ore, at least one alkali or alkaline earth metal salt, and at least one alumina-containing material in the presence of oxygen to form a calcined ore mixture, then leaching the calcined ore mixture with a solution comprising ammonium. sodium or magnesium chloride in the presence of oxygen to form a leached ore mixture, and contacting the leached ore with an acid to form a beneficiated ore.
La présente invention concerne un procédé d'enrichissement d'un minerai titanifère. Le procédé comprend les étapes consistant à calciner le minerai titanifère, au moins un sel de métal alcalin ou alcalino-terreux et au moins un matériau contenant de l'alumine en présence d'oxygène pour former un mélange de minerai calciné, puis à lixivier le mélange de minerai calciné avec une solution qui comprend du chlorure d'ammonium, de sodium ou de magnésium en présence d'oxygène pour former un mélange de minerai lixivié et à mettre en contact le minerai lixivié avec un acide pour former un minerai enrichi.
