What is Minerals 11 01392 about?

This article presents a novel method for extracting tantalum (Ta) and niobium (Nb) from coltan-bearing ore using ammonium bifluoride fluorination followed by sulfuric acid leaching. The study identifies optimal conditions for extraction, achieving approximately 94% Ta and 95% Nb recovery while minimizing environmental impact by reducing fluoride effluents. The findings suggest that this method could improve the efficiency and sustainability of Ta and Nb extraction compared to traditional fluoride-based proc
