Pilbara Minerals, Calix explore new lithium refining process

Pilbara Minerals has signed a memorandum of understanding with Sydney-based technology company Calix Limited to jointly undertake a scoping study to evaluate a new refining process, the Australian lithium miner said on Tuesday May 11.

If the results of the scoping study – which will run until late 2021 – are positive, the two companies will set up a joint venture to develop a demonstration plant to produce concentrate lithium salt from the miner’s Pilgangoora project, it said.

The proposed demonstration plant will likely involve the processing of fine-particle, lower-grade spodumene concentrate from the project to creating a low-carbon, concentrated lithium salt that could be further refined into lithium battery raw materials or potentially used as a direct feedstock for the production of lithium iron phosphate (LFP) cathode, it said.

The spodumene supply chain is ripe for innovation, with the industry continuing to move through a rapid growth phase while downstream sectors look to lower the carbon footprint of their end-products, Ken Brinsden, Pilbara Minerals’ managing director and chief executive officer, said.

“We look forward to working with Pilbara Minerals on this exciting project for the hard-rock lithium industry, and also other mining and processing companies in other minerals to improve their industrial processes, reduce costs and increase their sustainability,” Phil Hodgson, managing director of Calix, said.

The US trade roller coaster ride seems to be flattening, with signs of potential moderation and stability. It appears increasingly likely that our original expectation that the US Trump administration would primarily use the threat of tariffs as a negotiating strategy will be correct. While we do not expect to the US tariff position return to pre-2025 levels, we believe the overall US tariff burden is more likely to settle at around 10-30% globally rather than the elevated rates of 50-100% that seemed possible in recent weeks.

The recent US-China agreement to temporarily reduce tariffs is a major step for global trade, with tariffs on US goods entering China dropping from 125% to 10% and on Chinese goods entering the US decreasing from 145% to 30% starting May 14. While this has boosted markets and created optimism, key industries like autos and steel remain affected, leaving businesses waiting for clearer long-term trade policies.
The US-China trade truce announced on May 12 has brought cautious optimism to China’s non-ferrous metals markets, signaling a possible shift in global trade. Starting May 14, the removal of additional tariffs has impacted sectors like battery raw materials, minor metals and base metals such as zinc and nickel, with mixed reactions. While the improved sentiment has lifted futures prices and trade activity, the long-term effects remain unclear due to challenges like supply-demand pressures and export controls.
