THE CONFERENCE CALLER: As always, the annual New World Metals Investment Series is hosting a strong program of presenting companies.
This year, however, The Roadhouse has opted to look at the commodities being showcased by the presenters.
Antimony
The United States is currently on the look out for deliveries of many critical metals that were previously supplied by China and Russia, of which antimony is one.
China has imposed export restrictions on antimony to the extent that the reaction has been a very strong increase in the global price.
Antimony is used in a wide range of applications, ranging from flame retardants by enhancing the fire resistance in fabrics, plastics, and building materials.
Antimony plays an important role in the electronics industry for making diodes, Hall-effect sensors, and infrared detectors.
Antimony oxide improves the clarity and quality of glass and ceramics.
Copper
Copper exploration has been an ongoing constant in the Australian mining landscape and continues to be so.
Recent expenditure on copper exploration shows Australian exploration plays still enjoy the thrill of looking for, and the added thrill of finding this soft, malleable, and ductile metal with very high thermal and electrical conductivity.
According to the boffins at the Department of Industry, Science and Resources in their Commonwealth of Australia Resources and Energy Quarterly March 2024 the average spend on copper exploration in Australia rose to $169 million in 2023.
“This was around 19 per cent higher compared to the last year, and continues a general upward trend seen since 2017,” DISR said.
“Export volumes are forecast to reach 845,000 tonnes in 2023–24, little changed from 2022–23.
“However, due to a lower copper price, export earnings for 2023–24 are forecast to be around $12.1 billion, a 1.2 per cent contraction compared to 2022–23.
“Exports earnings (in real terms) are projected to grow 4.7 per cent annually, to reach around $16.8 billion by 2028–29.”
Gallium
Gallium is a critical metal used in the defence industry and computer chips with gallium chips anticipated to potentially replace silicon in semi-conductors, transistors, including electronic circuitry.
Gallium increases component speed and miniaturisation critical in generative AI and associated demands for semiconductors.
Once again, China has been central to the element’s recent surge in interest due mainly to an export ban implemented by that country in 2023.
Up to then, China was pretty much the sole gallium supplier to the semiconductor industry, producing around 98 per cent of the world’s supply of raw gallium.
Critical metal watchers anticipate USA, European and Asian, Sovereign states and semiconductor chip makers will be active in seeking reliable and secure supplies outside of China.
Graphene
Graphene was discovered in 2004 by some University of Manchester scientists playing with their graphite pencils and some sticky tape.
Their curiosity produced a substance 200 times stronger than steel that is 1,000 times lighter than paper.
Graphene conducts electricity better than any other material at room temperature making it a high contender for use in the battery industry.
Its exceptional conductivity has potential to produce graphene-based batteries that charge faster and last longer than the current lithium-ion favourites.
Graphite
Graphite is a soft, black mineral composed of carbon in a hexagonal crystalline structure, making it an ideal source for producing graphene.
Graphite is found in three different forms: in high-grade metamorphic rocks as disseminated crystal flakes; in veins or fractures as vein graphite; and in thermally metamorphosed coal deposits as amorphous graphite.
Graphite is a good electrical conductor and has a high fusion point and good lubricating properties.
It is used as an anode in batteries, as a refractory material in industries producing molten metal for crucibles and blast furnace linings, and to replace asbestos in brake shoes for heavier vehicles. Graphite is also used in pencils.
High Purity Alumina
High purity alumina (HPA) is a pure, high-grade form of non-metallurgical alumina or aluminium oxide (Al2O3).
Uses for HPA varies depending on its degree of purity, which can vary from 99.99 per cent (4N) and 99.999 per cent (5N), with some companies now seeking to produce 99.9999 per cent (6N) purity.
HPA is an essential compound for the manufacturing of LED (light-emitting diode) lights, lithium-ion batteries for electric vehicles and synthetic sapphire glass for wearable tech and smartphone camera lenses.
Indium
Most indium is used to make indium tin oxide (ITO), an integral ingredient of touch screens, flatscreen TVs and solar panels. This is because it conducts electricity, bonds strongly to glass and is transparent.
Indium nitride, phosphide and antimonide are semiconductors used in transistors and microchips.
Indium metal sticks to glass and can be used to give a mirror finish to windows of tall buildings, and as a protective film on welders’ goggles.
It has also been used to coat ball bearings in Formula 1 racing cars because of its low friction.
Lithium
If you haven’t heard of lithium by now, turn your phone on.
Lithium, a soft, very light, white metal, is found in spodumene rock formations, and Australia has some of the best-known deposits in the world.
Aside from its technological uses, lithium also has medicinal properties for psychotic medications.
Mineral Sands
Mineral sands (sometimes known as heavy mineral sands) contain concentrations of industrial minerals, such as rutile, ilmenite and zircon.
Other elements are sometimes present in the form of monazite and xenotime.
Rutile and leucoxene are sometimes blended to produce a high-grade titanium to be used as a feedstock to produce titanium dioxide and to make titanium metals for the aerospace industry.
Zircon is used as an opacifier for glazes on ceramic tiles, in refractories and for the foundry industry.
Nickel
Nickel has been delivering a world of pain to Australian participants with global mined nickel production up by 6.9 per cent year-on-year in the March quarter 2024.
Sounds good initially, until Indonesia is factored into the equation, which takes credit for the vast majority of that growth.
Because of its ability to process nickel further than Australian producers, Indonesia has more chance of exporting to China and is on track to further add to its current output.
The recent fall in nickel prices is expected to result in a substantial drop in Australia’s total mined and refined nickel production through to 2025–26.
We have already seen mine closures and reduced output from several Australian producers, as well as delays in planned projects.
Rare Earths
Rare earth elements are a group of seventeen chemical elements that occur together in the periodic table that is made up of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium).
Rare earth metals and alloys that contain them are used in many everyday use devices, such as computers, rechargeable batteries, mobile phones and magnets.
Many of the rechargeable batteries made with rare earth compounds are also used in electric vehicles.
Silica Sand
Silica sand is probably one of the more underrated of the world’s resources, being as it is the second most consumed globally after water.
Silica sand is demand as the primary ingredient for all glass and concrete, making it the foundational ingredient of the modern city.
Silica sand also has a crucial role to play in the global decarbonisation effort as high purity silica sand with a low iron content is needed for the high-tech flat glass used in solar panels and smart screen technology.
Silver
Silver has been giving gold a good run for its money of late, in fact the past twelve months has seen the second most shiny of the precious metals rising by more than 25 per cent this year to mid-August.
Silver is not often credited for its photovoltaic contribution, but being a quiet achiever the part it plays in generating solar power grew 64 per cent to a record high with analyst predicting strong growth to come.
There are many other uses for silver, including in medicine, the automobile industry – combustion and electric, as a water purifier, and is used in brazing and soldering.
A further approx. 280 million ounces (nearly 9,000 tonnes) of silver used in photography, silverware and jewellery manufacturing each year.
Tin
Tin is a white metal at room temperature that is soft and highly rust-resistant and fatigue-resistant.
Tin is non-toxic and highly malleable, which means it is easily shaped to suit the demands of its users.
Tin alloys easily with other metals, has a low melting point and is easy to recycle.
Of the many important uses for tin, the most common is to produce tinplate, or steel coated tin to be used for food packaging.
Tin and tin alloys are used also for solder, especially in the electronics industry.
It is commonly used as an alloy for bearing metal and as an alloy in metallic coatings.
Uranium
Uranium has found its way back to the national consciousness due to recent power policy shifts announced by the Federal Opposition.
Uranium is used to power nuclear power plants to generate electricity.
The energy produced by uranium creates steam that turns the turbines in the power plant which generate electricity.
Australia has the world’s largest Economic Demonstrated Resources of uranium and in 2022 was the world’s 4th largest uranium producer.
Australia, at present, has no commercial nuclear power plants and has very limited domestic uranium requirements.
Australia exports all its uranium production to countries that have signed bilateral safeguards agreement to ensure Australian uranium is only used for peaceful purposes and does not contribute to any military applications.
