TREATMENT OF TANTALUM- AND/OR NIOBIUM-CONTAINING COMPOUNDS

A process for treating a feedstock comprising tantalum- and/or niobium- containing compounds is provided. The process includes contacting the feedstock with a gaseous fluorinating agent, thereby to fluorinate tantalum and/or niobium present in the feedstock compounds. The resultant fluorinated tanta...

Zusammenfassung:	A process for treating a feedstock comprising tantalum- and/or niobium- containing compounds is provided. The process includes contacting the feedstock with a gaseous fluorinating agent, thereby to fluorinate tantalum and/or niobium present in the feedstock compounds. The resultant fluorinated tantalum and/or niobium compounds are recovered. La présente invention concerne un procédé de traitement d'une charge comprenant des composés contenant du tantale et/ou du niobium. Le procédé comprend la mise en contact de la charge avec un agent de fluoration gazeux, pour ainsi fluorer le tantale et/ou le niobium présents dans les composés de la charge. Les composés contenant du tantale et/ou du niobium fluorés obtenus sont récupérés.
