Beyond its use in the manufacture of sulphuric acid, sulphur dioxide also has many industrial uses, especially in the food, paper, pharmaceutical and refining industries.

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.

Pyrite roasting as a source of sulphuric acid continues to be a significant, albeit minor sector of the overall acid market.
