Niobium
Niobium becomes a superconductor at cryogenic temperatures. At atmospheric pressure, it has the highest critical temperature of the elemental superconductors at 9.2 K. Niobium has the greatest magnetic penetration depth of any element. In addition, it is one of the three elemental Type II superconductors, along with vanadium and technetium.Niobium and tantalum mineralisation are hosted in a distinct zone—the niobium-rich rare metals resource (also known as the Crown deposit). This Mineral Resource, defined separately from the main REE resource, totals 37.7 Mt at 1.07% Nb 2 O 5,0.024% Ta 2 O 5,0.30% ZrO 2,8.0% P 2 O 5,1.16% REO and 0.09% Y 2 O 3,with Tantalum Geoscience Australia

Tantalum Niobium Beneficiation Plant and Flowchart
The final concentrate contains 46% tantalum niobium and 5-6% tin, and the recovery rate is 86%. We also use this beneficiation process of tantalum niobium tin ore for our Rwanda customers, 51% tantalum and niobium, 7.1% tin, and 79% recovery are obtained, it creates huge profits for our customers. Forui has provided tantalum and The chemical formula of niobium-iron ore-tantalite is AB2O6, both of which are referred to as niobium-tantalum. Where A in the formula stands for iron and manganese, and B stands for niobium and tantalum. The magnetization rate of niobium-iron ore-tantalite is (22.1 to 37.2) × 10-6.

A study has been carried out on Ta and Nb recovery by a liquid-liquid extraction process using 4-methylacetophenone (4-MAcPh) as the organic phase. The 4-MAcPh was compared to methyl isobutyl ketone (MIBK) with respect to extraction efficiencies (D values) at different concentrations of H2SO4 in the aqueous phase. The We report extremely large magnetoresistance (MR) in an extended temperature regime from 1.5 K to 300 K in nonmagnetic binary compounds TaP and NbP.
