Tantalum has many diverse uses and so the supply chain that feeds these final products is complex. Mining for tantalum includes the beneficiation of the ore to a primary concentrate (4-7% Ta 2 O 5) or secondary concentrate (28% Ta 2 O 5). Refiners further improve the purity and produce pure tantalum in metal or powder form.Web
