The Middle East remains the world’s largest regional exporter of sulphur, with additional capacity continuing to come from both refineries and particularly sour gas processing.

Metso has secured a two-year life-cycle contract with Ideal Development for Manufacturing Industries (IDMI) for a new phosphate beneficiation plant at the Eshidiya phosphate mine in the south of Jordan.

Kazakh state gas company QazaqGaz says that work is progressing well and on schedule on the 1 billion m3 expansion project at the Kashagan Gas Processing Plant. A recent site report says that seven absorption columns have been installed at the sulphur treatment unit (each weighing between 50-170 tonnes); three sections of the smokestack have been installed at the sulphur recovery block, along with storage tanks and pumps for the heat carrier, instrumentation air, and nitrogen supply units; and a total of 2,177 t of process equipment has been installed. Welding works for tank assembly are ongoing, and over 12,000 meters of underground piping have been laid, and more than 38,000 cubic meters of concrete have been poured.

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.

President Yoweri Kaguta Museveni of Uganda has overseen the signing of signed an implementation agreement for the Uganda Refinery between the Ministry of Energy and Mineral Development, the Uganda National Oil Company (UNOC) and joint venture partner Alpha MBM Investments. Alpha MBM is a UAE-based company led by Sheikh Mohammed bin Maktoum bin Juma Al Maktoum, a member of the Dubai Royal Family. The agreement paves way for the design, construction and operation of the 60,000 bbl/d refinery to be undertaken at Kabaale. Construction is expected to take three years, with UNOC and Alpha MBM Investments as the project partners. The refinery, which will be East Africa’s first major crude processing plant, aims to reduce Uganda’s dependency on imported petroleum products and is expected to meet the local and regional demand for petroleum products.

• Global sulphur prices are expected to stay relatively stable as purchases in Asia slow down due to the closing of the purchasing window for the Chinese spring fertilizer application season.

CRU’s World Copper Conference was run at the start of April 2025 in Santiago, Chile, with the industry facing a crossroads. The Americas account for nearly half of the world’s mined copper, with South America producing 38% and North America contributing 10%. However, North American copper mines face cash costs 51% above the global average and 79% higher than those of their South American neighbours, positioning the region as one of the most expensive copper-producing areas globally. These high costs create a significant challenge, especially as securing a reliable copper supply has emerged as a geopolitical priority.

TotalEnergies has signed an agreement with the German developer RWE to supply 30,000 t/a of green hydrogen to the Leuna refinery for fifteen years, beginning in 2030. The green hydrogen will be produced by a 300 MW electrolyser, built and operated by RWE in Lingen. Green hydrogen storage will be provided locally. The green hydrogen will be delivered by a 600 km pipeline to the gates of the refinery and will prevent the site’s emission of some 300,000 tons of CO2 beginning in 2030. This is the largest quantity of green hydrogen ever contracted from an electrolyser in Germany.

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.”
