What You'll Learn
Gold
The first officially recognised gold discovery in Australia was made by assistant surveyor James McBrien on February 15, 1823, at Fish River, New South Wales. However, the gold findings were suppressed by the colonial government out of fear that it would reduce the workforce and destabilise the economy. Despite this, in 1847, William Tipple Smith, a mineralogist, discovered payable gold in New South Wales, and in 1851, Edward Hammond Hargraves, along with a team of miners, found gold near Bathurst, sparking the first Australian gold rush.
The gold rushes had a profound impact on Australia's population and economy. Between 1851 and 1871, Australia's population nearly quadrupled from 430,000 to 1.7 million, marking the beginning of Australia's multicultural society. The gold rushes also contributed to the development of rural areas, as miners, known as "diggers," flocked to often-isolated regions in search of gold. The economic impact was significant, with the gold mining industry in Western Australia accounting for A$17 billion in 2021-22, and the sale of 6.9 million troy ounces (214 tonnes) of gold during this period, the highest in two decades.

Cerium
In the steel industry, cerium plays a crucial role in removing impurities during steelmaking. Its ability to combine with unwanted elements helps produce high-quality steel with minimal defects. Additionally, cerium is used in the production of special alloys, enhancing the properties of metals. Cerium's versatility extends to polishing applications, with cerium oxide being a popular choice for achieving a high-quality finish on glass, stone, and even gemstones like agate, quartz, and opal.
Australia, being a significant mineral producer, recognizes the importance of critical minerals like cerium. Cerium's abundance and useful properties have attracted attention for potential innovative research and development. Its reactivity and ability to absorb UV radiation position it as a valuable element in addressing climate change concerns, particularly in water purification and UV protection applications. The exploration of cerium's potential in these areas could lead to significant advancements in mitigating the impacts of climate change.

Rare earth elements
REEs are used in a wide range of applications, including catalysts, anodes, light-weight super-strong magnets, colour phosphors for LEDs and display screens, abrasives, and energy converters. They are also critical components in many advanced and increasingly common technologies, such as mobile phones, electric vehicles, wind turbines, solar panels, rechargeable batteries, and clean energy infrastructure.
The demand for REEs is increasing as countries transition to renewable energy and green energy infrastructure. As of 2023, approximately 85% of the world's REEs are produced in China, which also consumes about 70% of that supply. However, there is a growing interest in diversifying the supply chain and reducing dependence on China. Australia, the world's second-largest producer of REEs after China, could be a major beneficiary of the increasing demand.
Australia's REE production primarily comes from Lynas Corporation's Mount Weld mine in Western Australia, with additional contributions from Northern Minerals Ltd.'s Browns Range project, also in Western Australia. Australian Rare Earths is also developing the Koppamurra Mine project on South Australia's Limestone Coast, which would be the only clay-hosted rare earth deposit in the country. Other projects, such as Arafura's Nolans project, aim to establish Australia as a rare earth producer independent of China by including a domestic separation plant.

Titanium
Australia is one of the top mineral producers in the world, and titanium is one of the many minerals that can be found in abundance in the country. Titanium is extracted from ilmenite and rutile sands, which are found in mineral sand deposits. These deposits are associated with modern and ancient beaches and dunes on the east, west, and southern coastlines of Australia.
In Western Australia, titanium mining began in the mid-1950s near Bunbury in the southwest of the state. Today, Western Australia is the largest producer of titanium in the country. The mining process involves dredging sands through a large suction pipe to separate the heavy minerals from the lighter sand particles. As the dredge moves forward, the clean sand tailings are pumped back to fill the mined area. Careful environmental rehabilitation is carried out progressively, with backfill tailings shaped to approximate the original landform. The original topsoil and any overburden are replaced, and the area is revegetated with local flora or pasture grasses.
Victoria hosts the greatest share of known rutile resources in Australia, with just over 50%, while Western Australia hosts nearly 50% of the known ilmenite resources. Australia accounts for approximately 40% of the global rutile resources and 19% of ilmenite resources. In 2021, Australia produced around 700 metric tons of titanium from mines, although this represented a decline from the previous year.
The abundance of titanium and other minerals in Australia has led to the development of various initiatives and resources related to geoscience and mineral education. The Australian Museum has a section dedicated to geoscience, and universities, scientific organizations, and government bodies have collaborated to create Earth and Environmental Science resources and teacher training. Additionally, organizations such as the Queensland Minerals and Energy Academy aim to support students' understanding of the resources sector and related career paths.

Mineral sands
In Australia, mineral sands are a significant resource, with the country possessing the world's largest deposits. The country is home to several active mineral sands companies, and these sands offer a substantial opportunity for economic growth and job creation, particularly in regional areas. Australia has an abundance of titanium mineral sands, with substantial shares of the world's ilmenite, rutile, and zircon resources. These minerals are used in various industrial applications, including the production of paint, titanium metal, and medical implants.
The three main elements extracted from mineral sand deposits in Australia are titanium from ilmenite and rutile sands, zirconium from zircon sands, and thorium from monazite. Garnet, magnetite, sapphire, diamond, and staurolite are also found in mineral sand deposits. Additionally, mineral sand deposits in Australia may contain rare earth elements, such as lanthanum, cerium, neodymium, erbium, and yttrium. These elements are used in wind turbine magnets, medical devices, electronics, and other products.
The states of Western Australia, New South Wales, South Australia, and Queensland are significant suppliers of mineral sands globally. The Murray Basin, covering parts of Victoria, New South Wales, and South Australia, is particularly notable for its rich resources of zircon and titanium minerals. Victoria has the potential to become a major global supplier of high-grade zircon mineral sands. Mineral sands deposits are also found in the Eucla Basin in South Australia and Western Australia, and there are identified deposits in Tasmania, Queensland, and the Northern Territory.
