What You'll Learn
Tungsten deposits in Australia
Australia has an 11% share of the world's tungsten resources, but its production is minor. Tungsten is a hard, brittle, steel-grey metal with the highest melting point of all pure metals, making it useful for many commercial and industrial applications.
Tungsten-bearing deposits occur in Western Australia, the Northern Territory, and along the eastern coast of Australia. O'Callaghans, in particular, is Australia's largest reported tungsten resource. It contains 0.26 Mt tungsten trioxide, 0.22 Mt copper, 0.38 Mt zinc, and 0.19 Mt lead.
In 2018, Australia's tungsten Ore Reserves remained unchanged while production increased, leading to a decreased reserve life. The Mt Carbine mine in Far Northern Queensland is Australia's only primary tungsten producer. In April 2019, Tungsten Mining commenced a prefeasibility study for mining and processing tungsten and molybdenum at the Mount Mulgine Project. The Mulgine Trench deposit is now the largest Inferred tungsten resource in Australia and the second largest total resource in the country.

Tungsten mining in Australia
Australia has an 11% share of the world's tungsten resources, but its production is minor. Tungsten is a hard, brittle, steel-grey metal with the highest melting point of all pure metals, making it ideal for many commercial and industrial applications.
Tungsten-bearing deposits occur in Western Australia, the Northern Territory, and along the eastern coast of Australia. O'Callaghans, in particular, is Australia's largest reported tungsten resource. It is found as a sub-horizontal layer at the contact between the limestone of the Proterozoic Puntapunta Formation and the Neoproterozoic O'Callaghans Granite.
Australia's only primary tungsten producer is EQ Resources, which operates the Mt Carbine Tungsten Mine in Far Northern Queensland. In 2018, Australia's one operating tungsten mine was Kara in Tasmania, with 2.9 kt of tungsten attributable to it.
There is potential for new resource definition and upgrades of existing resources in historical mining areas. Analysts forecast higher tungsten prices in the near term, with a potential supply deficit and a need to boost tungsten exploration outside of China, which currently holds about 51% of the world market share.

Tungsten alloys
Alloying small quantities of tungsten with steel greatly increases its toughness. During the sintering process, the nickel diffuses into the tungsten, producing an alloy. Tungsten alloys are also commonly produced from rich concentrates, typically with 65% or more tungsten trioxide (WO3).
Some examples of tungsten alloys include:
- HA170C, HD 17, Dens21, CMW 1000, K1701, M1000
- MT-17D DieAlloy: 90% tungsten, 4% nickel, 4% molybdenum, 2% iron
- MT-17F: 90% tungsten, 7% nickel, 3% iron
- MT-18C: 95% tungsten, 3.5% nickel, 1.5% copper

Tungsten's economic importance
Tungsten is a chemical element with symbol W and atomic number 74. It is a metal that occurs naturally on Earth, almost exclusively in compounds with other elements. It has the highest melting and boiling points of all pure metals, making it useful for many commercial and industrial applications.
The economic importance of tungsten lies in its exceptional physical properties, particularly its hardness and resistance to high temperatures. It is used in the production of hard metals, alloys, and tungsten carbide compounds, which are employed across various industries.
Hard Metals and Alloys
Tungsten and its alloys are among the hardest of all metals. Its ability to bind metals such as cobalt, nickel, and iron is significant. These hard metals, often consisting of tungsten carbide and metals of the iron group, are used for tools, drilling equipment, and wear-resistant parts. They are also used in cutting and stamping applications, as well as in the reinforcement of other materials.
Tungsten Carbide
Tungsten carbide, with a hardness of 9.5 on the Mohs scale, is a crucial tungsten compound. It is used to impart wear resistance to cast iron and the cutting edges of saws and drills. Additionally, it forms hard, refractory, and chemically inert compounds with elements like boron, nitrogen, and silicon. Tungsten carbide is also used in very hard and tough dies, tools, gauges, and bits.
Strategic Importance
The strategic importance of tungsten has been recognised for decades, with the United States maintaining a government stockpile since the 1940s. During World War II, tungsten played a significant role in political dealings, as it was an important raw material for the arms industry, used in both weapons and equipment production.
Other Applications
Beyond its use in hard metals and alloys, tungsten finds applications in a variety of industries. It is used in lamp filaments, electrical and electronic applications, and even in aerospace for the fabrication of rocket-engine components. Tungsten nanowires also show potential in nanoelectronics, pH probes, and gas sensors.
In summary, tungsten's economic importance stems from its unique physical and chemical properties, which make it valuable for a wide range of industrial applications, from metalworking to electronics and aerospace.

Tungsten's use in electronics
Tungsten is widely used in the electronics and power industries due to its unique properties. It has the highest melting point of all metal elements, a very high density, and its hardness is close to that of a diamond. It also has good electrical and thermal conductivity, a low coefficient, and a low evaporation rate. These characteristics make tungsten ideal for use in various electronic applications.
One of the primary uses of tungsten in electronics is in the manufacture of light bulb filaments. Tungsten wire has a high luminous rate and long service life, making it perfect for incandescent lamps, halogen lamps, and iodine tungsten lamps. The high melting point of tungsten allows it to withstand the high temperatures generated during the lighting process without deforming or melting, ensuring a long-lasting and reliable light source.
Another important application of tungsten in electronics is in the production of electronic tubes and instruments. Tungsten wire is used in direct heating cathodes and grids of electronic oscillating tubes, as well as in indirect heating cathode heaters in various electronic devices. The high electron emission ability of tungsten makes it well-suited for these applications.
Additionally, tungsten compounds find use in the electronics industry as catalysts and inorganic colours. For example, tungsten disulfide is employed as a lubricant and catalyst in the synthesis of gasoline, while bronze-coloured tungsten oxide is used in painting. Calcium or magnesium tungsten is also used in fluorescent powder and phosphors.
The unique properties of tungsten, particularly its high melting point and hardness, make it an essential material in the electronics industry, contributing to advancements in lighting technology, electronic devices, and various other applications.
