Enhanced tantalum and niobium recovery from fine-grained low-grade Abu Dabbab ore using Falcon concentration and magnetic separation.

ABSTRACT: Tantalum (Ta) and niobium (Nb) possess unique properties that make them invaluable across various industries. However, their similar chemical characteristics and natural co-occurrence challenge their separation. This study aims to optimize the recovery of Ta and Nb from fine-grained, low-grade Abu Dabbab tantalite ore (Egypt) using integrated Falcon centrifugation and magnetic separation. The beneficiation process commenced with gravity separation via a Falcon SB40 concentrator, which was optimized through a Box-Behnken design to assess the feed rate, fluidization water, and centrifugal field effects. Under optimal conditions (89.30 g/min feed rate, 4.40 psi fluidization water, 200 G centrifugal field), a concentrate grade of 2.00% Ta₂O₅ and 0.705% Nb₂O
