As more focus extends to a circular economy, there are industry wide discussions on whether future global sulphur demand will be challenged by the energy transition and decarbonisation. Hannes Storch, Collin Bartlett and Marcus Runkel of Metso discuss how the recycling of pyrite tailings could address some of these issues.

Brazilian phosphate producer Galvani says that it has begun work on its major phosphate expansion in Bahia state, including a new production plant at Ceará, in partnership with Indústrias Nucleares do Brasil (INB). The company aims to reduce Brazil’s northern and northeastern regions’ reliance on imported fertilizers. The first phase includes $133 million of investment, including $76 million for new phosphate mining at Irecê, and $38 million for Luís Eduardo Magalhães factory, also in Bahia. This expansion will take capacity from 600,000 t/a to 1.2 million t/a by 2026. The expansion at Luís Eduardo Industrial Complex includes expansion of sulphuric acid capacity from 165,000 t/a to 250,000 t/a.
Dundee Precious Metals says that it has sold the Tsumeb smelter, including all associated assets and liabilities, to China’s Sinomine Resources Group for $49 million. Sinomine Resources Group is a Chinese company founded in 1999. Its main business and operations cover four segments: EV-lithium material development and utilisation, rare and light minerals (caesium and rubidium) development and application, geo-tech services and mining property development. Dundee Precious Metals will transfer all assets debt-free and cash-free, subject to normal working capital adjustments. The transaction is subject to customary closing conditions, including approval under the Namibia Competition Act and approvals required from Chinese regulatory authorities for overseas investments, and is expected to close in Q3 2024.
Digitalisation is making a strong impact in the process industry and is providing an opportunity to have a positive impact on the production KPIs. Metso’s Metals & Chemical Processing Business reviews the impact of digitalisation in the sulphuric acid industry today and discusses the concept of a future pit-to-port system within a digital eco-structure.
Morocco’s OCP is continuing to expand its phosphate fertilizer production capacity. This includes the construction of new sulphur-burning acid capacity to support phosphate production and provide carbon-free power.
In January, Kazakh uranium producer Kazatomprom warned of potential adjustments to its 2024 uranium production due to challenges with sulphuric acid availability and construction delays at new uranium mining operations. In a statement the company said that its projected uranium output for 2024 will be between 21,000 t/a and 22,500 t/d U3 O8 , around 20% lower than the amount it had been expecting to be able to mine. Kazatomprom’s uranium output was 21,100 t/a U3O8 in 2023, down 1% on 2022 figures, with output flat during 4Q 2023. While it said it had sufficient inventory in stock to cover contracted deliveries in 2024, there could be problems for 2025 deliveries.
Pyrite roasting as a source of sulphuric acid continues to be a significant, albeit minor sector of the overall acid market.
Freeport Indonesia has inaugurated the $250 million expansion at its PT Smelting copper smelter in Gresik, East Java, in a ceremony attended by Indonesian president Joko Widodo.
