Resilience in the tantalum supply chain - ScienceDirect

2018-2-1  Tantalum ore is composed of both tantalum and non-tantalum containing minerals, and the Ta 2 O 5-equivalent content is typically 0.02–0.04 percent. Low-grade tantalum ore is physically concentrated (beneficiation) to a concentrate of 20–40 percent Ta 2 O 5 -equivalent at the mining site before sale to smelters ( Linnen et al., 2014 ).
