Indonesia is increasing the royalty rates that the government takes on metals mined within the country. The Indonesian government has proposed a tiered royalty structure on nickel ore sales, ranging between 14–19%, depending on the prevailing nickel price. This would replace the current flat rate of 10%. A 14% rate would apply when nickel prices are below $18,000 /t, increasing progressively to 19% for LME prices above $31,000 /t. The royalty is calculated based on revenue from nickel ore sales.

Due to an increasingly challenging market, Nyrstar will indefinitely lower production at its Hobart zinc smelter in Tasmania by around 25%. The plant’s zinc capacity is 280,000 t/a. “This decision follows a thorough and extensive review and is a direct response to deteriorating market conditions and financial losses being sustained by Nyrstar Australia,” the Trafiguraowned company said. “Nyrstar’s Australian assets continue to face significant financial challenges due to several external factors including worsening conditions in raw material markets, negative treatment charges and increased costs.”

Two dam failures at the Morowali industrial park in Indonesia have killed three people. On March 16, during heavy rains, the PT Huayue Nickel Cobalt tailings storage facility at the Morowali industrial park failed, and tailings flowed into the Bahadopi River. The breach flooded facilities at the industrial park and the village of Labota. Five days later another tailings dam inside the industrial park, owned by PT Qing Mei Bang (QMB) New Energy Materials, collapsed, killing three workers. The affected tailings facilities store acidic waste from high pressure acid leaching (HPAL). It is estimated that for every ton of nickel, HPAL processing generates 150-200 tons of tailings. The affected facilities use filtered tailings, where some of the water is removed from the tailings before they are placed the dam. However, heavy rains, landslips and seismic activity appear to have affected the stability of some of the dams.

The Tunisian cabinet has met to review its future programme for phosphate production, transport, and processing for the 2025-2030 period, as well as the current situation of the Tunisian Chemical Group and its work plan for the same period, according to a government statement. The prime minister stressed the need to develop phosphate production as a national resource and a cornerstone of the national economy that must regain its role and position in supporting state revenues and wealth creation, including increasing production capacity, processing, and exports, while investing in modern technology to enhance productivity, exploring new export markets, and prioritising environmental considerations.

Axens says that it has completed the expansion of its Axens Catalyst Arabia Ltd site, aimed at providing local and regional partners with the latest tail gas treatment catalysts, in addition to the site’s legacy catalyst hydroprocessing manufacturing capacity. This makes Axens is the first and only company to produce tail gas treatment catalysts in the Middle East. The company says that the expansion consolidates its capacity to serve its regional customers to meet regulatory requirements and maximise sulphur recovery by up to 99.9%, minimising SOx emissions. The production site supplies the region’s refining and gas industries with the latest generation of Axens’ catalysts, capable of operating at lower temperatures than conventional catalysts, and resulting in lower energy consumption.

Astron Energy, a subsidiary of Glencore, says that it will spend $328 million to upgrade its South African crude oil refinery in order to comply with the country’s upcoming cleaner fuel regulations. The investment aims to bring the facility in line with South Africa’s Clean Fuels II standards, which mandate lower sulphur content in both petrol and diesel. The 100,000 bbl/d refinery near Cape Town is one of only two remaining operational refineries in the country. Astron says that construction work is already under way for a gasoline hydrotreating plant that will reduce sulphur levels to Euro 5 (<10ppm sulphur) specifications. The regulations have been delayed to July 2027 due to concerns over the cost of upgrading existing refining infrastructure. n

Avenira has secured an A$7.56 million strategic investment from majority shareholder Hebang Biotechnology to progress its Wonarah phosphate project in Northern Territory. The investment, in which Hebang will acquire 1.08 billion shares priced at A$0.007 each, will boost its equity holding in Avenira to 49%. Hebang has also agreed to provide Avenira with an unsecured drawdown loan facility to be repaid on completion of the placement or after the date of the first drawdown.

Indonesian nickel miner Merdeka Battery Materials (MBMA) and partners have signed definitive agreements to construct a high-pressure acid leach (HPAL) plant on the Morowali industrial park, Sulawesi. The unit will have a nameplate capacity of 90,000 t/a of contained nickel in mixed hydroxide precipitate (MHP). PT Sulawesi Nickel Cobalt (SLNC) will construct and operate the plant adjacent to the existing HPAL plant operated by PT Huayue Nickel Cobalt (HNC). SLNC will source and process laterite nickel ore through a 20 year commercial agreement with MBMA's SCM mine, starting from the commissioning date. An ore preparation plant will be built at the SCM mine to enable ore transportation via pipeline to the SLNC processing plant at IMIP. The total combined investment for constructing SLNC (including interest incurred during construction) is expected to be approximately $1.8 billion according to Merdeka. Construction of the project commenced in January 2025 and is expected to reach commissioning stage within 18 months.

Kuwait’s state owned Kuwait Oil Company (KOC) has issued a tender for companies to bid on construction of the second phase of its gas sweetening facility at booster station BS 171 in West Kuwait. Thirty-two companies have been pre-qualified to bid for the $390 million engineering procurement and construction (EPC) contract for the project. Phase II will involve the construction of two processing trains, each with a capacity to produce 60 million scf/d of sales gas from sour gas with an H2S content of 4%. Sulphur recovery from the project will come from two separate 100 t/d trains with a total capacity of 65,000 t/a of molten sulphur.
