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.

Tantalum mineral concentrates may contain from two to more than five different tantalum-bearing minerals from the same mining area.The sale of tantalum mineral concentrates is based on a certified analysis for the tantalum oxide (Ta 2 O 5) they contain,with a typical range from 20% to 60% depending on the mine source.

As tantalum, tin and tungsten deposits are generally hard rock, and low grade (particularly tantalum), they are considerably more difficult to process than mineral sands. Mining is either open cut or underground and requires drilling and blasting. The broken rock then requires crushing and grinding to liberate the minerals prior to separation.

Prior to the shift, Australia & Brazil were the major tantalum mining countries. Beginning in 2007, the DRC, Rwanda, and other African countries became the major sources of tantalum production. The production shift from Australia was a result of high extraction costs and an unfavorable exchange rate, which meant that mining tantalum ore in ...
