Title
(EN) PROCESSES FOR PREPARING TITANIUM OXIDE AND VARIOUS OTHER PRODUCTS
(FR) PROCÉDÉS POUR LA PRÉPARATION D'OXYDE DE TITANE ET DE DIVERS AUTRES PRODUITS
Abstract
(EN)
There are provided processes for preparing various products from various materials. For example, such processes are effective for extracting titanium and various other metals from various materials, thereby allowing for preparing products such as titanium chloride and titanium oxide. These processes can comprise leaching the starting material with HCl so as to obtain a leachate and a solid. The solid can be treated so as to substantially selectively extract titanium therefrom while the leachate can be treated so as to substantially selectively recover a first metal chloride therefrom.

L'invention porte sur des procédés pour la préparation de divers produits à partir de diverses matières. Par exemple, de tels procédés sont efficaces pour l'extraction de titane et de divers autres métaux à partir de diverses matières, ce qui permet de cette manière de préparer des produits tels que du chlorure de titane et de l'oxyde de titane. Ces procédés peuvent comprendre la lixiviation de la matière de départ avec de l'HCl afin d'obtenir un lixiviat et un solide. Le solide peut être traité afin d'extraire en grande partie sélectivement du titane de celui-ci alors que le lixiviat peut être traité afin de récupérer en grande partie sélectivement un premier chlorure métallique à partir de celui-ci.
