Niobium - an overview | ScienceDirect Topics

The total counts recorded in forming niobium dihydride were comparable to those observed in hydriding LaNi 5.Again, abrupt changes in the slope of dE/dX vs. H/M (Fig. 5) correspond well with the phase boundaries from other studies of the niobium-hydrogen system [11].The pressure-temperature composition studies covered the transition from the α-niobium metal phase to the β-niobium hydride .Recovery Leaching of Niobium from Metallurgical Residues ...Niobium was recovered by acid-alkaline leaching from metallurgial residues. The experimental results indicate that effects of different leaching system and leaching conditions on the Nb recovery were different. Separation of niobium and impurities such as iron, manganese, calcium and silicon is essential for Nb recovery. Acid leaching distributed metals between the solid and solution.Blue River Tantalum and Niobium Pro. | Commerce ResourcesMetallurgical testwork shows that the ferrocolumbite and pyrochlore which host the tantalum and niobium mineralization are amenable to a two-stage process of conventional flotation and proven refining processes with estimated recoveries of 65% to 70%. The first step of the process uses grinding followed by flotation to produce a concentrate.Tantalum Processing | TIC - Tantalum-Niobium International ...For example, a secondary processor may buy K-salt, metallurgical grade tantalum metal powder or tantalum ingot, then apply further chemical and/or metallurgical processing (e.g. reduction, or vacuum arc melting, or powder injection moulding) and produce final products such as oxides, capacitor grade powder, or metal products such as tubes or wire.(PDF) On the metallurgical effects of Niobium in cast iron ...Niobium has metallurgical functio ns for both, ...
