Abrégé

A process for heat treating a lithium containing material with reduced dust generation comprising: (a) directing a lithium containing material to a heating vessel; (b) heating the lithium containing material in the heating vessel with a controllable source of electromagnetic energy directed toward the lithium containing material to cause a phase transformation in said lithium containing material; and (c) extracting gas and dust from the heating vessel into a gas extraction system. A system for the heating the lithium containing material is also disclosed. The process and system allow higher impurity lithium materials to be treated while reducing the burden of an accumulating dust load during calcination operations.

Classes IPC  ?

• C22B 26/12 - Obtention du lithium
• C22B 1/02 - Procédés de grillage
• C22B 3/06 - Extraction de composés métalliques par voie humide à partir de minerais ou de concentrés par lixiviation dans des solutions inorganiques acides
• C22B 4/02 - Métaux légers

A process for heat treating a lithium containing material with reduced dust generation comprising: (a) directing a lithium containing material to a heating vessel (1); (b) heating the lithium containing material in the heating vessel (1) with a controllable source of electromagnetic energy (5) directed toward the lithium containing material to cause a phase transformation in said lithium containing material; and (c) extracting gas and dust from the heating vessel (1)a into a gas extraction system (6). A system (10) for the heating the lithium containing material is also disclosed. The process and system allow higher impurity lithium materials to be treated while reducing the burden of an accumulating dust load during calcination operations.
