Tantalum recovery process

WebWith the gradual reduction of tantalum resources, this kind of recovery becomes increasingly important. At present, the amount of tantalum recovered annually (Ta2O5) accounts for more than 30% of tantalum production. It is a difficult task to extract tantalum from alloys especially superalloys. WebHistorically, Marropino’s tantalum recovery was relatively poor. Typically less than 50% of tantalum contained in the mine’s ores was recovered, with the remainder either left in waste dumps or lost during processing. As a result, the University of Glasgow was commissioned to undertake a project to assist Noventa to improve its tantalum ...
