The economic and strategic importance of multi-metals processing
27.05.2025 - 07:30
Mandala was commissioned by Nyrstar to provide an independent summary of the significance of lead and zinc refining in Australia. This report finds that Australia’s existing capabilities are a gateway to domestic critical minerals processing, but fundamental shifts in the global industrial policy landscape are undermining Australia’s current and future processing capabilities.
Australia has the largest reserves of lead and zinc globally and an established refining capability, ranking as the third largest exporter of refined and intermediate lead and the second largest exporter of refined zinc in the world.
Nyrstar is Australia’s major lead and zinc producer, with two multi-metals smelters: Nyrstar Port Pirie and Nyrstar Hobart. Both facilities are core pillars of the local industrial base and the Australian economy, contributing $1.7 billion gross value added in 2024 and supporting 6,648 full time equivalent jobs across the country.
Lead and zinc refining is an essential precursor to capturing and processing five critical minerals: antimony, bismuth, tellurium, germanium, and indium.
Nyrstar Port Pirie is Australia’s only producer of refined lead with critical minerals extraction capacity.
Lead and zinc smelters around the world are operating in challenging economic conditions. Maintaining lead and zinc refining capabilities outside of China will become increasingly challenging. If other countries exit lead and zinc smelting, China could achieve monopoly power in this market and maintain majority control of the global supply of associated critical minerals.
Australia’s lead and zinc smelting capabilities are fundamental to Australia’s ambition to leverage its high-quality mineral deposits and become a leading exporter of value-added critical minerals.
Maintaining a robust domestic industry has economic, strategic, security, industrial, and societal benefits.

The Stagnant Nation: Lifting Australia’s Dynamism
Australians are going backwards on real wages and income. Real wage growth has fallen from 0.6 per cent in the 2000s to -0.7 per cent today, the slowest rate since the 1990s recession. Weak productivity growth is a key driver. Productivity growth has dropped from 2.2 per cent in the 1990s to just 0.1 per cent today. The Productivity Commission has pointed to declining economic dynamism as one cause for weak growth, with fewer businesses starting, growing and competing. We confirm declining economic dynamism across five key dimensions and estimate that reversing this decline seen since the mid-2000s could see a GDP uplift of $101 billion per year over the next decade. Our analysis finds that regulation could account for around 20 per cent of declining dynamism. Reducing regulatory burden to late-2000s levels could see GDP uplift of at least $20 billion per year over the next ten years.

Demonstrating the economic benefits of Airwallex in Australia
Mandala's latest research, commissioned by Airwallex, quantifies the direct and indirect economic benefits of Airwallex in Australia. Airwallex supported $4.6 billion in economic benefits in 2025, a figure roughly equivalent to 2 per cent of the Australian tech sector's contribution to GDP. Of this, $2.5 billion flows directly to platform businesses through productivity gains, new market access and cost savings, with the remainder reaching the broader economy as those benefits move through customers' supply chains. Airwallex supports 29,000 jobs across the Australian economy, and a quarter of economic benefits flow to regional, rural and remote areas. Small and medium businesses capture the largest share of any business segment on the platform, $2.1 billion annually, or $200,000 in economic benefits for the average SMB each year.

Power to the people
Mandala’s latest research examines how Greater Manchester turned devolved power into economic growth, why it worked, and what it could mean if similar powers were extended across England. Since devolution began in 2009, Greater Manchester’s economy has grown by nearly 45%, outperforming both the rest of England and the UK as a whole. Greater control over funding and policy has enabled the Mayor and Greater Manchester Combined Authority (GMCA) to coordinate investment in transport, housing, skills and economic development around local priorities. This has supported a 41% increase in bus journeys, recycled £300m of government capital into around £1bn of housing investment, delivering 11,000 dwellings, and increased employment in key sectors by over a quarter, compared with 14% across England. Integrating health and social care has also improved life expectancy, with the largest gains in self-reported health in the least healthy neighbourhoods. If local and combined authorities in England had these powers and replicated Manchester, we estimate an annual boost to the economy of up to £80bn, over 93,000 new homes, and £3.1bn in additional economic activity from improved life expectancy.

The Hidden Economy: Addressing Australia’s Domestic Work and Care Divide
Mandala’s research, in partnership with DoorDash Australia, examines the scale and distribution of Australia's unpaid household labour, the real costs it imposes on individuals and the economy, and the role that emerging technologies and policy reform could play in reducing and more equitably sharing that burden.
