A World of Minerals in Your Mobile Device - USGS

Tantalum, from the source mineral tan-talite, is added to capacitors to regulate voltage and improve the audio quality of a device. Wolframite is a source of tungsten, which acts as a heat sink and provides the mass for mobile phone vibration. Battery Spodumene and subsurface brines are the sources of lithium used in cathodes of lithium-ion ...

Resilience in the tantalum supply chain - ScienceDirect

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 ).
