Tantalite's greatest difference from columbite is it's much greater specific gravity 8.0+ compared to columbite's 5.2. The business involves the sourcing of Tantalite Ore, milling and packaging same for export. The commodity would be packaged in rakes of 50/80/100 KG depending on buyer requirement. Delivery would be FOB, Free on Board.

Typically, the ore is concentrated to around 5% Ta 2 O 5 at or near the mine site. Some operations will take this primary concentrate and further concentrate to 28% Ta 2 O 5, the globally recognized specification for tantalite concentrate for which you may see a quoted price that has varied between US$50 and $150/lb over the past two decades.

The general chemical formula of niobium tantalite is AB2O6, and the two are collectively referred to as niobium tantalite. A is iron and manganese, and B is niobium and tantalum. The magnetic susceptibility of niobium tantalite is (22.1～37.2)×10-6. The dielectric constant of ferroniobium is 10-12, and the dielectric constant of tantalite is 7-8.
