Melting sulphur
The deficit in the sulphur market has led to a new focus on melting down and selling stockpiles of sulphur around the world. From Kazakhstan to Canada, stocks of sulphur have been shrinking.

Prices in sulphur markets have been climbing rapidly for several weeks now due to short supply, reaching their highest levels for early two and a half years, since July 2022. A major cause has been widening Ukrainian drone and missile strikes against Russian oil and gas facilities. In particular, drone strikes in September on the Astrakhan and Orenburg natural gas plants led to Russian sulphur exports being cut drastically, first from around 400,000 tonnes per month to only 100,000 tonnes in October, and then to zero from the 1st of November, as Russia implemented a ban on exports of sulphur used in fertilizer production which was projected to last at least until December 31st. “This decision will stabilise shipments of raw materials to the domestic market to maintain current mineral fertilizer production volumes and ensure the country’s food security,” the government’s press service reported. The restriction applies to the export of liquid, granulated, and lump sulphur. It remains to be seen whether exports of Kazakh material from Ust Luga will be affected, but some Kazakh sulphur is now being sold via Iran.
This issue of Sulphur magazine contains a preview of CRU’s Sulphur + Sulphuric Acid conference in Woodlands, Texas, which is being held from November 3rd to 5th this year, giving delegates the opportunity to meet and discuss some of the trends which are continuing to change the sulphur and sulphuric acid industries. Some of this is echoed in our editorial coverage this issue; the rise of electric vehicles and the continuing electrification of society is changing demand for metals and impacting upon both sulphur and sulphuric acid markets alike. As CRU’s principal analyst Peter Harrison discusses on pages 36-37, battery demand for nickel is leading to a surge in new nickel leaching capacity in Indonesia which is drawing in greatly increased volumes of sulphur, while rising demand for copper is leading to additional volumes of smelter acid from China, India and Indonesia which are impacting the merchant market for acid, as detailed by CRU’s Viviana Alvorado on pages 38-40. In the United States, new lithium mines will require additional sulphur (see pages 22-23). Rare earths and battery metal recovery will form a major topic on the first day of the Sulphur + Sulphuric Acid conference, with speakers from Lithium Americas, one of the pioneers of the new US lithium industry.
Phosphate prices have been at high levels for a couple of years now, and talk at the recent International Fertilizer Association (IFA) meeting in Monaco was that it was not only continuing to support higher sulphur prices in spite of oversupply in the sulphur market, but that there seemed to be no prospect of it falling in the short term.
I am writing this freshly returned from the Sulphur Institute’s annual Sulphur World Symposium in Florence (for more on that see pages 24-25), where one of the topics causing some excitement was the anticipated commissioning of a demonstration plant for Travertine Technologies’ new Travertine Process. The plant is due to be commissioned at the Sabin Metals site near Rochester, New York in mid-2025 at a cost of $10.7 million. Capacity is put at “hundreds” of tonnes per year of gypsum processed, and removing “tens” of tonnes per year of CO 2 from the atmosphere.
The past few weeks have seen sulphur prices spiking after a steady rise since 3Q 2024. At time of writing, delivered prices to a variety of locations were around $280/t c.fr, their highest level since mid-2022 when the price of commodities of all kinds jumped in the wake of the Russian invasion of Ukraine and subsequent sanctions. Steady buying from Indonesia and China, the two largest importers of sulphur, appears to have supported the market, in China’s case mainly for phosphate production as well as a variety of industrial processes, and in Indonesia’s case to feed the high pressure acid leach (HPAL) plants that are producing nickel for the battery and stainless steel industries. Although Chinese buying has dropped off slightly since Lunar New Year, and demand has also slackened in India, Indonesia’s appetite continues unabated, having tripled its nickel production since the start of the decade to become the world’s largest producer, representing 60% of global supply in 2024.
The start of a new year is a traditional time to take stock of the previous 12 months and look ahead to the next. In this regard, CRU’s most recent annual client survey, conducted at the end of December last year, makes interesting reading as to your own concerns for 2025 and beyond. There were numerous responses across commodity and financial sectors, and broadly based worldwide, if slightly skewed towards Europe and North America, but across all of these the key worry for the coming year clearly emerged as trade tariffs and protectionism. This is perhaps unsurprising, given incoming US president Donald Trump’s avowed intent to impose blanket 20% tariffs on all goods entering the US, and up to 60% on China. While most clients did not think tariffs would rise as much as some of Trump’s rhetoric might suggest, most expect rises of 5-10% across the board, and Asian businesses are most concerned. CRU’s most recent position paper on US tariffs highlights some of the internal political and legal challenges in implementing these, but does acknowledge that some rises will be inevitable, and may well produce the kind of reciprocal measures last seen in the previous Trump administration’s trade war with China and the EU in 2018.
OCP’s recent award of a contract to Worley Chemetics for three new greenfield sulphuric acid plants has confirmed the phosphate giant’s plans for its new Mzinda Phosphate Hub in Morocco, one of the largest investments in new phosphate capacity anywhere in the world over the next few years. It is part of a number of new investments under way in Morocco as OCP continues to expand its already considerable phosphate facilities. Three new fertilizer lines came onstream at Jorf Lasfar in 2023 and 2024, each with a capacity of 1 million t/a of diammonium phosphate (DAP). The Mzinda mega-project will add another 4 million t/a of triple superphosphate (TSP) capacity by around 2028-29, and will relieve some of the issues that OCP has in importing ammonia for DAP production, as TSP only requires phosphate rock and phosphoric acid. There is also an additional 1 million t/a of TSP capacity under construction at Jorf Lasfar, which is expected to be completed next year, and OCP also announced last year that it would build an integrated purified phosphoric acid (PPA) plant at Jorf Lasfar. The first phase of the project consists of 200,000 t/a of P2 O5 pretreated phosphoric acid capacity, 100,000 t/a (P2 O5 ) of PPA capacity, and 100,000 t/a of technical MAP (tMAP) capacity. The site will also be home to downstream production of phosphate salts and lithium iron phosphate (LFP) capacities. The initial plants will be delivered starting in mid-2026, carrying through into 2029, constructed in conjunction with JESA, a joint venture between OCP and Worley.
One of the biggest areas for new sulphuric acid demand in the past few years has been in nickel processing plants, particularly in Indonesia. A decade ago, incoming president Joko Widodo took a strategic decision that the country needed to try and capture more of the value chain from its mining and mineral industry, which was focused at the time on exports of aluminium, copper and nickel ores and concentrates, mainly to China. Over the past 10 years, the export of raw ores has been progressively restricted and companies instead compelled to build downstream processing plants for the metals. With China the main recipient of Indonesian ores, much of the investment in metals processing in Indonesia has been via Chinese companies.
While the events of the past few years have been difficult for Europe on many fronts, including a wholesale realignment of its energy sources with the restriction of access to Russian oil and gas, the effect on Europe’s sulphur production seems likely to be just as profound.
