What are Critical Minerals?

Tungsten is recognised as a critical mineral by the US , Eu, Australia and Japan.*

These minerals play a pivotal role in driving the economy. This is partially due to helping advance low-emission technologies and safeguarding national security. These minerals are of paramount strategic importance due to their supply chain fragility.

The definition of the term has evolved to align with the changing needs of modern society. In ancient times, it referred to basic resources like salt and iron. Today, it encompasses rare metals and minerals such as lithium, tungsten, and cobalt. These are instrumental in powering today's digitalized society and many industries' high-tech capabilities.

Tungsten Sources

Wolframite is one of two main tungsten sources and is a critical mineral.

Wolframite

Wolframite or iron manganese tungsten oxide (Fe,Mn)WO₄ is a primary tungsten ore. This critical metal ore contains 76.5% tungsten oxide. It's typically found around tin and granite deposits within quartz veins in many locations. The mineral wolframite is highly valued as the main source of tungsten. The largest wolframite reserves are found in China. These reserves make up over half the global supply of this critical mineral ore.

Scheelite is a critical mineral used as a primary tungsten source.

Scheelite

Scheelite or calcium tungstate CaWO₄ is a primary tungsten ore. This critical metal ore contains 80.6% tungsten oxide. Scheelite is mined all around the world with large reserves found in Brazil and China. This ore was originally given the name tungsten by the Swedes translating to “heavy stone” before the name was coopted as a term to describe the metal. Meanwhile, the mineral was renamed scheelerz or scheelite.

Recycled tungsten scrap is now a major tungsten source and offsets critical mineral reliance.

Recycled Tungsten

Tungsten scrap is regarded as a very valuable critical metal resource. This is due to the high tungsten content of scrap material compared with primary ore sources. Recycled tungsten makes up a valued percentage of the tungsten destined for use in high-speed and temperature steels. Recycled scrap tungsten is also fairly simple to process. This is by very similar chemical processes to those which isolate tungsten when processing ores.

FAQs

  • These minerals are vital resources that play a significant role in the economy. They are also key in the manufacturing of low-emission technologies, and national security. These essential minerals are considered critical due to their potential supply chain fragility. As we rely on advanced technologies and green initiatives more and more, the demand for these minerals continues to grow.

  • Minerals deemed ‘critical’ and ‘strategic minerals’ are often used interchangeably. However, there is a subtle distinction. Strategic minerals hold additional significance in the context of national security and defense applications.

  • Critical minerals refer to a group of naturally occurring substances. These substances are essential for various industrial, technological, and economic applications. These can include both metallic and non-metallic elements, such as lithium, cobalt, graphite, and tungsten. Critical Metals refer to metallic elements deemed essential for specific industry applications.

  • Critical minerals are instrumental in the production of sustainable technologies. These include electric vehicles (EVs), renewable energy systems, and energy-efficient electronics. Embracing these metals facilitates a transition towards a greener and more eco-friendly future.

  • The list displayed above is sourced from the latest US Geological Survey 2022. The list is updated every 3 years with a number of minerals updated based on the changing needs of society.

  • Companies can develop a comprehensive Minerals Strategy. This would include diversifying suppliers, exploring new sources, and collaborating with industry partners. Such a strategy would ensure a stable and reliable supply. We aim to diversify ferrotungsten supply chains globally amidst growing supply uncertainty. This uncertainty is characterised by Chinese industry dominance and geopolitical tensions expected to continue rising.
