Zambian Copper Smelter Plans to Extend Production Shutdown, Further Squeezing Production and Chemical Supply

April 21, 2026 - On April 20 (Monday), two industry sources said that Zambia's two largest copper smelters and sulphuric acid producers plan to carry out extended maintenance shutdowns later this year, which will further squeeze the country's copper production and the supply of sulphuric acid used to process copper and cobalt.  The Iran war has disrupted global supplies of this critical acid and other leaching chemicals, forcing mines in neighboring Congo, the world's largest cobalt producer and second-largest copper producer, to reduce usage or consider production cuts.  Zambia's mining ministry said that, as Africa's second-largest producer of critical metals needed for clean energy technologies, the country's copper smelters generate approximately 2 million mt of sulphuric acid annually, mainly as a by-product for use by local mines, with the surplus exported to the DRC.

First Quantum Minerals' country head in Zambia said that Zambia's own sulphuric acid inventory had been severely depleted, leaving virtually no export capacity. Meanwhile, miners in neighboring DRC were also struggling to cope with tightening chemical supplies.

 

Mopani's long-overdue maintenance

A chemicals trader said that although copper smelters typically shut down for about 30 days each year for routine maintenance, Mopani and Chambishi copper mines will face longer shutdowns this year.  A mining executive said Mopani copper mine had not undergone maintenance for some time and plans to shut down for three days in June, followed by an extended shutdown of approximately 40-45 days, August-mid-September.

 

The chemicals trader said Chambishi copper mine plans to shut down for approximately two months throughout August, but did not elaborate on the reasons for the planned extended shutdown.  Zambia tightened controls on sulphuric acid exports this month, requiring traders to obtain permits. The country said the move was aimed at protecting domestic industries.

First Quantum's Zambia country director Anthony Mukutuma said the measures were reasonable but exports were unlikely in the short term.

 

Global copper supply expected to decline

Global copper supply will tighten this year as years of underinvestment have constrained mine production growth. Zambia produced 890,346 mt of the red metal last year, falling short of the 1 million mt target.  Meanwhile, according to shipping data, Congo's copper exports declined in Q1 this year.  The mining executive said Mopani copper mine was operating well below its 225,000 mt finished copper capacity due to a shortage of copper concentrates caused by years of underinvestment. The executive said the main owner, UAE-based International Resources Holding, was simultaneously developing and mining the mine, which forced intermittent production stoppages and further constrained output.


China moves to ban sulphuric acid exports as Iran war hits supply

April 11, 2026 - Prices have already surged in Chile, which buys over one million tonnes of Chinese sulphuric acid every year  China has indicated it will halt exports of sulphuric acid from May, hitting metals and fertiliser industries already strained by raw material bottlenecks resulting from the Iran war.  Some sulphuric acid producers in the country recently received notifications about the change, and one large buyer has been told about it by their Chinese supplier, according to sources familiar with the matter, who asked not to be identified discussing confidential information. The ban will cover sulphuric acid that’s a by-product of copper and zinc smelting in China.  Sulphuric acid prices have been rising since the start of the Iran conflict, as the effective closure of the Strait of Hormuz blocks sulphur shipments from the Middle East, where it’s a product of oil and gas refining. The region produces one-third of the world’s sulphur, a raw material used to make sulphuric acid that’s essential for some copper extraction and phosphate fertilisers.  China’s move to conserve sulphuric acid supplies during the peak crop-planting season will put further pressure on the market. That squeeze will hit the copper-mining industries in key producers such as Chile, the Democratic Republic of Congo and Zambia.  Pricing agency Argus Media first reported the Chinese ban on Thursday (Apr 9), saying the restriction could last throughout 2026.  China’s Ministry of Commerce did not immediately respond to a request for comment.

BASF starts up the world’s first production plant for 3D-printed catalysts

March 20, 2026 - BASF has started up the world’s first production plant for catalysts based on X3D® technology at its Ludwigshafen site, Germany.  With the commissioning of this facility, BASF is scaling the additive manufacturing of catalysts to an industrial level and strengthening its leading role in innovative solutions for the chemical industry.  Utilising X3D technology, catalysts can be produced with optimally designed geometries that combine high mechanical stability with an open structure. This significantly reduces pressure drop in reactors while simultaneously increasing the catalytically active surface area. As a result, customers achieve higher reactor throughput and improved product quality at substantially lower energy consumption compared to conventional catalysts.  BASF has been supplying X3D catalysts to production plants for several internal and external customers for many years. The versatile technology can be applied to a broad range of catalyst materials, including precious and base metal catalysts as well as various support materials. The new production plant in Ludwigshafen provides the foundation for making this technology more widely available and for further shortening development and market introduction timelines.  In 2025, the Chinese-based fine chemical company An Hui Jintung filled its production plant with BASF’s sulfuric acid catalysts O4-115 X3D. “The plant started up smoothly, and plant performance has significantly improved compared to before. Production achieved a record high, generating substantial economic benefits for our company. We will continue our collaboration with BASF to promote catalyst upgrades and replacements across additional units,” said Eter Zhu, General Manager at An Hui Jintung.


Chinese, Jordanian firms ink deal to build sulfuric acid plant in S. Jordan

 

February 11, 2026 - Jordan's Indo-Jordan Chemicals Company Ltd, a subsidiary of Jordan Phosphate Mines Company (JPMC), on Wednesday signed a 193-million-U.S. dollar deal with China's East China Engineering Science and Technology Co., Ltd. (CNCEC-ECEC) to construct a concentrated sulfuric acid plant in southern Jordan.  According to a JPMC statement received by Xinhua, the plant will be constructed in the Shidiya area, with a designed annual production capacity of about 900,000 tons.  The project is scheduled to be completed within 30 months by CNCEC-ECEC and will be implemented in line with high international technical, engineering and environmental standards, the statement said.  Under the agreement, sulfuric acid produced at the plant will be used to support the expansion of the Jordanian company's phosphoric acid production, raising its annual output capacity from 330,000 tons to 550,000 tons.  JPMC Chairman Mohammad Thneibat said the deal reflects the company's continued efforts to expand investments and upgrade operations, in line with Jordan's broader drive to attract foreign investment and strengthen industrial competitiveness.  He noted that the project represents a strategic step for the company to enhance added value in the phosphate industry, increase production efficiency, and create job opportunities during both construction and operation phases.  For his part, Meng Chenzhou, CEO of CNCEC-ECEC, described the project as a model of industrial cooperation between Chinese and Jordanian companies, adding the company hopes to maintain long-term cooperation with its Jordanian partners to develop more projects at both the regional and international levels.


Chemical Spill Triggers Mass Fish Death in Kazakhstan

 

February 6, 2026 - Sulfuric acid may have caused a mass fish die-off in Shymkent, Kazakhstan, according to preliminary findings following laboratory tests of water samples taken from the Badam River.  Specialists detected elevated sulfate levels in the samples, pointing to an acidic environment that experts believe led to the death of aquatic life.   The pollution is suspected to be linked to an industrial discharge, The Caspian Post reports via Kazakh media.  According to initial assessments, the acidic solution was released into a sewer pipe, which later ruptured. Due to the aggressive chemical composition of the wastewater, the discharge could not be stopped immediately, allowing contaminated runoff to flow into the river for several hours.  Authorities are now working to identify the enterprise responsible for the pollution. Liability will also extend to the organization that owns and maintains the damaged sewer infrastructure.  Environmental officials urged residents to treat nature responsibly and to promptly report any signs of environmental violations to the relevant services.  “Based on our analyses, specialists from the department have launched an inspection of Vodnye Resursy Marketing. It will later be determined which enterprise discharged the acidic solution. Even releasing acid into a sewer pipe is prohibited-it must be neutralized, and local treatment facilities must be in place,” said Akmaral Nysanbekova, head of the testing laboratory at Shymkent’s Department of Ecology.


Cabinet approves export controls on sulphuric acid to avert shortage of chemical

February 5, 2026 - Cabinet has approved the introduction of a permit-based export system for sulphuric acid, aimed at ensuring sufficient supply for domestic industries and supporting the country’s copper production.  Zambia is one of the leading producers of sulphuric acid in the region; however, in August last year, the country experienced a shortage of the chemical, which is a critical input for the mining, manufacturing, and agriculture sectors.  The shortage resulted into a disruption of copper processing.  Minister of Information and Media, Cornelius Mweetwa, revealed at a briefing that, in a move to prevent a repeat of the shortage, Government has put measures in place to secure the local supply.  “Cabinet approved the issuance of a Statutory Instrument on the introduction of a permit-based export system on sulphuric acid, in order to ensure sustained availability for domestic industries, safeguard industrial output, and support Zambia’s copper production and economic growth agenda,” Mr Mweetwa said.  The permit system means companies cannot export sulphuric acid freely without approval. This ensures that enough of the chemical stays in the country to meet the needs of local industries that use the chemical.  “In August 2025, the country experienced a shortage of sulphuric acid, which had begun to disrupt production in copper processing.  “In light of the unresolved shortage of sulphuric acid, Cabinet has decided, going forward, to utilise a permit-based export regulation mechanism so as to address the critical issue of the local shortage of sulphuric acid,” Mr Mweetwa said.  He said that the permit-based approach is part of the government’s commitment to sustaining industrial growth and supporting Zambia’s strategic economic priorities.


Phosphate Hill back online after big wet impact

February 3, 2026 - Dyno Nobel’s Phosphate Hill plant, 150km south of Mount Isa, has resumed fertiliser production in the wake of North-West Queensland flooding impacting key transport routes.  The interruption to supply chains, particularly the extended closure of the railway line to Townsville, saw the company suspend fertiliser manufacturing at the site.  The Townsville to Mount Isa line reopened at the weekend after closures on the key route stretching back to December 29.  “During this time, mining activities continued at the Phosphate Hills site, the Mount Isa plant continued producing on sulphur burn and product held in on‑site storage was transported by truck to Townsville when roads reopened,” a Dyno Nobel (ASX:DNL) spokeswoman said.  “Available stock held at Townsville was also dispatched to supply customers.  “The Phosphate Hill site team has used this time to undertake maintenance activity originally scheduled for February.  “Following the rail line reopening, the Phosphate Hill plant has now resumed production.”  Key rail line back in business after extended cutsThe North-West Queensland mining site manufactures monoammonium phosphate (MAP) and diammonium phosphate (DAP) fertilisers.  Around this time last year, the owner was forced to cut production forecasts due to sulphuric acid supply interruptions and last wet season’s flooding on the Mount Isa rail line.

Kazakhstan powers ahead in global uranium market


February 2, 2026 - Kazakhstan increased its uranium production by 11% in 2025, reaching 25,800 tons, state nuclear company Kazatomprom announced.  Production is expected to rise further in 2026, with forecasts ranging between 27,500 and 29,000 tons, contingent on adequate availability of sulfuric acid, a critical component in uranium processing, Caliber.Az reports, citing the company.  Last year, a new sulfuric acid plant was commissioned in southern Kazakhstan by a Kazakh subsidiary of the Russian fertilizer producer EuroChem. The facility has already begun production, ensuring a more stable supply of the chemical for the country’s uranium sector.  Kazakhstan, one of the world’s largest uranium producer, continues to expand its output, reinforcing its strategic position in the global nuclear fuel market.


Port expansion in Chile clears first environmental hurdle

 

January 23, 2026 - Chile’s environmental evaluation agency SEA accepted to review a US$50 million (mn) proposal from port operator Terquim to expand a terminal in Mejillones municipality (Antofagasta region).  The project entails increasing the capacity of the terminal’s liquid fuel installations by adding two tanks each for sulfuric acid and diesel storage.  The sulfuric acid tanks will have capacity for up to 423meach, while the diesel tanks will handle up to 850meach, according to the environmental impact assessment (EIA) presented by Terquim.  Other works include incorporating equipment for the transference of green ammonia, including a system of three 1,500m pipelines: one for transferring the product, another for vapor recovery, and a third for cooling.  Lastly, the EIA proposes upgrades to the terminal’s liquefied petroleum gas (LPG) installations, such as a new septic pit with capacity for up to 10m3, two new 30m2 warehouses for dangerous substances and hazardous waste respectively, and an expanded potable water distribution system.  Construction works are expected to start in April 2027.
