Abstract

Zur Herstellung von Titandioxid-Konzentraten durch Ent­ fernen des Eisens aus Eisenoxide aufweisendem titanoxidhal­ tigem Material mit Hilfe von mindestens 70 Volumen% Chlor enthaltenden Gasen überführt man mindestens 0,1% des im ti­ tanoxidhaltigen Material enthaltenen Eisens mit Hilfe eines Re­ duktionsmittels bei Temperaturen von 500 bis 1300°C in den nullwertigen Zustand. Das teilweise reduzierte titanoxidhaltige Material setzt man bei Temperaturen von 300 bis 1300°C mit den chlorhaltigen Gasen um. Als Reduktionsmittel können Kohlenstoff oder Gase wie Wasserstoff, Erdgas oder Kohlen­ monoxid oder ihre Mischungen dienen.
