LKAB has begun construction of its new demonstration plant for processing phosphorus and rare earth elements at Luleå. The facility is the first in a planned industrial park and, says LKAB, marks an important step in the company's ambition to diversify its business with new minerals. The supply of phosphorus for mineral fertilizers is essential for food security in Sweden and the EU, while rare earth elements are critical for the electrification and digitalisation of society, such as the production of permanent magnets for electric vehicles and wind turbines. The $75 million demonstrator plant is planned to become operational in 2026. The aim is to further develop and verify the process for utilizing material flows from iron ore production in Gällivare, where apatite concentrate is produced for further refinement and production of critical minerals in Luleå. Through a stepwise expansion, the operations can then be scaled up with additional processing facilities over time, aiming for full operation during the 2030s. Once fully operational, the industrial park’s production will be approximately seven times Sweden’s needs and 6% of the EU’s demand for phosphorus in agriculture. Currently, there is no mining of rare earth elements in Europe.

Aurubis AG has reported operating earnings before taxes of euro130 million ($134.8 million) for the first quarter of its fiscal year 2024/25, up around 17% on the figure for the equivalent period of last year (€111 million or $115.1 million). The company’s Custom Smelting & Products (CSP) segment posted €125 million ($129.7 million) in EBT compared with €107 million ($111 million) in the previous year. CSP comprises production facilities for processing copper concentrates as well as for manufacturing and marketing standard and specialty products, such as cathodes, wire rod, continuous cast shapes, strip products, sulphuric acid and iron silicate, via smelters in Hamburg and Pirdop, Bulgaria. The company attributes the higher EBT to higher metal prices, considerably increased sulphuric acid revenues, and robust earnings from copper product sales and lower costs, which more than compensated for a year-over-year decline in treatment and refining charges with lower concentrate throughput.

Glencore says it is working with the Queensland government to secure the future of the Mount Isa copper smelter. The company had previously indicated that it would close the smelter in 2030, but recent media reports suggest that the government is looking at assistance to keep the smelter operational, which currently treats more than 1 million t/a of copper concentrate and supplies sulphuric acid to other industries locally, including phosphate production.

Chemical Industries of Senegal (ICS) has launched two projects to increase phosphate fertilizer production in the country. At a company event, new managing director Mama Sougoufara said that between 2014 and 2023, ICS has expanded production to 2 million t/a of phosphate rock, 600,000 t/a of phosphoric acid, and 250,000 t/a of phosphate fertilizer. The new expansions, with a price tag put at $475 million, include a plant at Mbao to increase fertilizer output from 250,000 t/a to 600,000 t/a, as well as a new phosphate rock processing plant, increasing output by 300,000 t/a. The company has seen its financial situation improve in recent years thanks to its takeover by the Indorama Group, though the Senegalese government retains a 15% stake.

Tight supply limits availability as China maintains export restrictions.

Philippine Associated Smelting and Refining (PASAR) has put its plant on Leyte Island into care and maintenance to evaluate the operation amid what it termed as increasingly challenging market conditions.

Yara says that it plans to wind down production of phosphate fertilizers and sulphuric acid at two sites in Brazil; Cubatão and Paulínia. The sites are expected to cease production by 3Q 2025, as part of what Yara describes as a strategy to concentrate on more sustainable operations focused on its main activity: the production of nitrogen fertilizers. At Cubatão, the suspension will affect unit 3 and the phosphate plants of unit 2, while units 1 and 2, responsible for the production of nitrogen, in addition to the mixer (unit 5), will continue to operate normally. Yara reported a net loss of $290 million in 4Q 2024, down $536 million from the $246 million profit it made in 4Q 2023. Revenues are down 11% for the year, leading Yara to announce a cost reduction and investment program of $150 million, with the aim of optimising its operations and focusing on strategic areas to ensure long-term sustainability. At the same time, the company has begun renewable ammonia production at Cubatão.

The Chinese government has issued a development plan for the country’s copper smelting industry covering the years 202527 which is looking to reduce the level of overcapacity in the sector. New copper smelters must now control sufficient copper mine supply via ownership or equity stakes to cover their production requirements, something few smelters do at present. Chinese smelter output has reached record levels, with treatment charges falling to historically low levels as producers compete for copper concentrate – China imports around 85% of its copper concentrate. Meanwhile more smelter capacity is planned, with around 1 million t/a of new capacity scheduled for 2025. The country aims to boost domestic copper mine resources by 5% to 10% in three years to secure raw material supply, according to the government plan. China will also encourage copper smelters to sign long-term purchase agreements with global miners, boost imports of copper blister and anode, and encourage scrap imports.

Metso has launched its new Cu POX leaching process for the copper extraction industry. The company says that, as ore compositions change due to depletion of deposits and increasing environmental and efficiency demands, this solution not only maximises copper recovery but also reduces environmental impact.

Nickel Asia Corp. (NAC) says that it has completed the sale of its 15.6% stake in Coral Bay Nickel Corp. to its Japanese partner Sumitomo Metal Mining. Nickel Asia says that the sale has been due to “unfavourable market conditions” for the high pressure acid leach (HPAL) nickel processing plant. Although Coral Bay is regarded as one of the most efficient HPAL units in the world, nickel prices have been extremely volatile over the past few years and stood a 4-year lows in January at around 15,000/t, their lowest level since September 2020. Nickel Asia still owns a 10% stake in the Taganito HPAL Nickel Corp.
