What Are Rare Earths? A Mining Jobs Guide to Australia's Industry

Rare earths get mentioned in the news more than almost any other commodity right now. Here's what they actually are, where Australia fits in, and what it could mean if you're looking at a career in the sector.

If you've been following mining news at all this year, you've probably noticed "rare earths" and "critical minerals" turning up constantly, usually next to words like "supply chain," "China," and "strategic." For job seekers, it's worth understanding what's actually behind the headlines, because this is one of the few parts of the resources sector genuinely being built out in real time in Australia, rather than just being mined and shipped as-is.

First, what are rare earths?

Rare earths are a group of 17 metallic elements (things like neodymium, dysprosium and lanthanum) that aren't actually all that rare in the earth's crust. What's rare is finding them in deposits concentrated and clean enough to be worth extracting economically, and separating them from each other, which is chemically difficult and has historically been dominated by a handful of countries.

They matter because small amounts go into things that are hard to replace: the magnets in electric vehicle motors and wind turbines, batteries, smartphones, guided weapons systems, and a long list of other modern technology. A wind turbine or EV motor typically needs only a few kilograms of rare earth material, but there's no easy substitute for it.

Where Australia actually sits

Australia isn't the world's biggest rare earths producer, that's still China by a wide margin, but it's a genuinely significant one: around fourth in the world for both reserves and annual production, producing roughly 13,000 tonnes in 2024 compared with under 2,000 tonnes as recently as 2011. That's a real, fast-growing industry, not a rounding error.

The bigger story for Australian workers isn't the mining side, it's processing. China currently handles the large majority of the world's rare earths refining, even material that isn't mined there, because separating the individual elements requires specialised chemical processing infrastructure that took decades to build. Australia has historically dug the ore up and shipped it offshore for that step. That's now changing, with government and private investment (including a recent US-Australia critical minerals agreement worth billions) specifically aimed at building processing capacity onshore.

The actual projects, and what they mean for jobs

• Lynas Rare Earths (Mt Weld, WA) - Australia's largest and longest-running rare earths mine, near Laverton. Lynas has also built the country's first rare earths cracking-and-leaching processing facility, at Kalgoorlie, meaning some of the traditionally offshore chemical processing work now happens here.
• Iluka Resources (Eneabba, WA) - Australia's first fully integrated rare earths refinery, currently under construction, targeting commissioning in 2027. This is a processing plant, not a mine, which means a different mix of roles again: process operators, chemical and metallurgical trades, plant maintenance.
• Arafura Rare Earths (Nolans, NT) - A fully permitted, construction-ready project north of Alice Springs, targeting neodymium and praseodymium for magnets.
• Hastings Technology Metals (Yangibana, WA) - Targeting first production in 2026.
• Northern Minerals (Browns Range, WA) - Positioned to become a significant producer of dysprosium, a heavy rare earth used in high-performance magnets, outside of China.

That spread across mining, chemical processing and refining is the real takeaway for anyone weighing up the sector: rare earths roles aren't only drill-and-blast and haul trucks. Kalgoorlie's and Eneabba's processing facilities need process engineers, chemical plant operators, metallurgists and instrumentation technicians alongside the usual site trades, skill sets that are transferable from other processing-heavy commodities like alumina or lithium.

What this means if you're weighing up a role here

It's still an early-stage industry. Several of the projects above (Eneabba, Nolans, Yangibana) are under construction or pre-production rather than established, decades-old operations. That usually means more hiring activity as projects ramp up, but also more schedule risk than a mature iron ore or gold operation, projects can and do slip.

Processing skills are increasingly valuable, not just extraction skills. As Australia builds out onshore refining, chemical and process engineering backgrounds are likely to matter more in this commodity than in most other Australian mining categories.

It's a geopolitically-backed growth area. Government-level agreements and funding specifically targeting critical minerals processing (rather than general mining investment) suggest this sector has policy tailwinds behind it in a way that ordinary commodity cycles don't always have.

As with any commodity, the usual rule applies: look at the specific project's funding and construction status, not just the sector-wide story, before you commit to relocating your life around it.
