METHOD FOR EXTRACTING THE TANTALIUM AND / OR NIOBIUM FROM AN ACOUSIC ACUTE PHASE AND METHOD OF RECOVERING THE TANTALIUM AND / OR NIOBIUM FROM AN ACIDIC ACUTE PHASE USING THIS EXTRACTION PROCESS |
| abstract |
The invention relates to a process for extracting tantalum and / or niobium from an aqueous acid phase, which comprises at least one step comprising contacting the aqueous phase A1 with an organic phase, and then separating of the aqueous phase A1 of the organic phase, and which is characterized in that the organic phase comprises a (C1-C4 alkyl) -acetophenone as an extractant. The invention also relates to a method for recovering tantalum and / or niobium from an acidic aqueous phase and implementing this extraction process. Applications: Treatment of concentrates of natural or urban ores containing tantalum and / or niobium for the production of tantalum and / or niobium in metallic form or in the form of compounds such as Ta2O5 and Nb2O5 pentoxides. |
