British Startup Plans to Restart Australia’s Only Manganese Smelter for EV Market

British Firm Proposes Revival of Liberty Bell Bay Smelter

MELBOURNE, Aug 24 (Reuters) - Natrium Redox Technologies, a green technology startup based in Britain, said on Monday it had made a firm proposal to the Tasmanian government to acquire and restart Australia's only manganese smelter, to supply global battery and electric vehicle markets.

Background: Closure and Administration of the Smelter

EY Parthenon said last month the Liberty Bell Bay (LBB) Smelter would close after a proposed sale fell through. The smelter, formerly owned by British industrialist Sanjeev Gupta's GFG Alliance, entered voluntary administration in March and liquidation this month after suspending operations mid-last year.

Negotiations and Government Involvement

"We have engaged with EY Parthenon and the Tasmanian government on this proposal for six months. We have also briefed the federal government," Natrium Redox Technologies said in a statement.

"Our restart proposal seeks shared input of funds with government to the level of A$15 million ($10.75 million) for a 16-week restart period and a continuation of the existing electricity contract."

Official Responses and Site Control

In a statement, Tasmanian Business Minister Felix Ellis said potential pathways for the site had been put forward, but no transaction has been completed and no commitments were made.

"EY currently controls the site as liquidator, which includes decisions about its sale," he said. EY Parthenon had no immediate comment.

Technological Innovations and Production Plans

Natrium Redox Technologies said it planned initially to use conventional smelting techniques to restart the smelter before building a pilot plant that would use new technology to produce high-purity, low-emissions manganese powder.

Green Technology and Environmental Impact

The process uses liquid sodium in place of coking coal to strip oxygen from manganese ore. It operates at lower temperatures than traditional smelting and does not produce carbon emissions.

Value Addition and Market Position

The new technology would add 20% to 40% to the site's production and lift the smelter up the value chain from being a conventional alloy smelter into one of the highest-value manganese operations in the world by producing battery-grade materials, the company said.

"Battery grade materials sell for a far higher price than conventional alloys, securing LBB’s financial future and ensuring it remains a strategically important critical minerals asset for Australia."

Economic and Environmental Benefits

Its proposal would provide more than 200 jobs previously linked with the smelter, as well as secure others during construction, Natrium Redox Technologies said.

It also has a proposal to reprocess a A$210 million environmental liability that has accumulated from decades of slag and waste, removing environmental liabilities from the government, it said.

Urgency of the Restart

The company emphasised that time was of the essence because the longer furnaces are idled, the harder and more expensive a restart would become.

Key Takeaways

  • Natrium Redox has made a firm offer to acquire and restart Australia’s only manganese smelter in Tasmania, proposing A$15 million in co‑funding for a 16‑week restart period plus continuation of the electricity contract.
  • The Liberty Bell Bay smelter entered voluntary administration in March, failed to secure a buyer, was liquidated in early August, and resulted in over 200 job losses, though the site retains strategic value for critical minerals.
  • Natrium plans to initially use conventional smelting and then transition to a novel low‑emission sodium‑based process that could boost output by 20–40%, produce high‑purity battery‑grade manganese, and address A$210 million in environmental liabilities.
