The mineral group tantalite [(Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or “columbite-tantalite” in many mineral guides. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite’s 5.2). Iron-rich tantalite is the mineral tantalite-(Fe) or ferrotantalite and manganese-rich is tantalite-(Mn) or manganotantalite.

Tantalite is also very close to tapiolite. Those minerals have same chemical composition, but different crystal symmetry orthorhombic for tantalite and tetragonal for tapiolite.

Tantalite is black to brown in both color and streak. Manganese-rich tantalites can be brown and translucent.

Our trade process spreads across CIF and FOB depending on the buyer’s preference.

Here’s what they entail:

1). Cost Insurance and Freight (CIF): Here, the seller will handle everything from loading the vessel, paying for insurance, and sending the product to wherever the buyer wants it delivered.

2). Freight On Board (FOB): Here, the seller pays for the transportation of the goods to the port of shipment, plus loading costs, while the buyer pays the cost of marine freight transport, insurance, unloading, and transportation from the originating port to the final destination.
