The Saudi Arabian Mining Company (Ma’aden), the largest multi-commodity firm in the Middle East, 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 Ras Al Khair in Saudi Arabia.
The plant will use sulfur for the 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.
“This pioneering patent, combined with our new CO2 capturing complex, underscores Ma’aden’s commitment to sustainability,” said Hasan Ali, Executive Vice President, Ma’aden Phosphate. “We look forward to working with Metso and thyssenkrupp Uhde to develop this important project that will truly change and reduce the carbon footprint of our phosphate business.”
“The new concept for the phosphogypsum processing will be a major step forward in the fertilizer industry, contributing to sustainability targets, such as waste recovery and limiting global warming,” said Hannes Storch, Vice President for Metals and Chemicals Processing at Metso. “Metso will contribute to the project with our extensive expertise and experience in the field of fluid bed, gas cleaning and sulfuric acid solutions.”
