Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0.01 to 1 percent tantalum pentoxide, which is equivalent to 0.1 to 10 kilograms per metric ton. As a result, to produce concentrates of tantalum, tantalite ore must be separated from other minerals in the ore.

The single largest operating tantalum mine is the Mibra operation of Companhia Industrial Fluminense in Nazareno.This mine has the capacity to produce 220 tonnes Ta 2 0 5 per year which equates to approximately 15% of current global primary production,although the latter are at historically relatively low levels.

Rare earth ore. (Reference image by US Government, Wikimedia Commons ). Physicists have created a new ultra-thin, two-layer material with quantum properties that normally require rare earth compounds.

Open-pit tantalum mining is a type of strip mining in whichthe tantalum ore deposit extends very deep in the ground,necessitating the removal of layer upon layer ofoverburden and ore.In many cases, logging of trees and clear-cuttingor burning of vegetation above the ore depositmay precede removal of the overburden.

The tantalum supply chain can be relatively lengthy in terms of raw material traceability. Originating from the mining of ore to the manufacturer of the finished product, whether electrical equipment or turbine blades, the supply chain can include intermediaries such as traders and distributors and be sourced from multiple suppliers at any step in the process.
