Tungsten
Tungsten - A Critical Element - EU, US, UK, Canada
Tungsten (also known as Wolfram), is a Transition Metal chemical element with symbol (W) that has extreme physical characteristics including:
The highest tensile strength of any metal
The highest melting point of any metal
A density of 19.3, comparable to Uranium and Gold
Tungsten Monocarbide alloy (WC) has a hardness close to that of diamond
These unique properties lead Tungsten to be used in a diverse range of applications including:
Engineering, Defence, Tooling (as WC), Oil & Gas Exploration, Minerals Exploration and Production, Medical Technology, Electronics, Power Engineering, Lighting, the generation of Very High Temperatures, Coating and Joining Technology, & Sports Technology
The principal application for Tungsten which comprises approximately 60% of global Tungsten consumption1 is in the production of cemented carbides also called hard metals, the main constituent of which is Tungsten Monocarbide (WC)
Global Statistics
Global consumption of Tungsten is around 100,000 tonnes per annum, comprised of approximately:
75% from primary Sources
25% from Secondary/Recycled Sources1
Mineral occurrences of Tungsten are most typically formed of deposits of Scheelite which form approximately two thirds of global tungsten mineral deposits
Mineral Resources and Reserves are commonly reported in percent Tungsten Tri-Oxide (WO3)
Typical Resources range in grade from 0.2% to 0.5% WO3
High Grade Resource range in grade from 0.5% to 1.5% WO3
China is the world’s largest producer accounting for 71,000 tonnes or 80% of global production2
