The Saudi Arabian Mining Co. (Ma’aden) has signed a frame agreement with Metso and thyssenkrupp Uhde for the development and licensing of a phosphogypsum processing solution for the calcination plant at the industrial city of Ras Al Khair in Saudi Arabia.

The plant will use sulfur for calcination of phosphogypsum and include technologies for CO2 capturing with lime produced from the calcination. The process will lead to a reduction in CO2 emissions across Ma’aden’s phosphate business, making it more sustainable in the long term. Ma’aden’s patented concept will allow the company to use new technology to reduce carbon emissions and recycle phosphogypsum into a useful resource. Metso’s role in this development is to provide technology knowhow for this unique process.

Hasan Ali, executive vice president, Ma’aden Phosphate, said the agreement “puts us at the forefront of innovation, turning what was once leftover material into a valuable resource, while significantly reducing CO2 emissions. It’s a giant leap towards a sustainable future.”
