January 8, 2016 - The Saudi Arabian Mining Co. (Ma’aden) has announced the approval of a Saudi Industrial Development Fund loan of Saudi Arabian riyal 4bn ($1bn*) for the Ma’aden Waad Al Shamal Phospahte Co. (MWSPC).  The loan is split into four facilities, each of which provides separately for the construction of an ammonia plant in Ras Al Khair, a diammonium phosphate (DAP) plant in the same city, a sulphuric acid plant in Waad Al Shamal and a phosphate plant, likewise in Waad Al Shamal.  Ma’aden said that the loans would complete the debt financing of its phosphate joint venture. Saudi Basic Industries Corp. (SABIC) and US-based Mosaic Co. retain 15% and 25% stakes in the business, respectively.

March 4, 2014 - DuPont Sustainable Solutions is pleased to announce that MECS, Inc., a wholly owned subsidiary of DuPont, has been awarded the sulfuric acid technology license by the Saudi Arabian Mining Company (Ma’aden) for its Waad Al Shamal Phosphate Project. MECS, Inc. will provide the sulfuric acid technology and proprietary equipment for this three-line, 15,150 metric-tonne-per-day sulfuric acid facility. Ma’aden has selected a consortium led by long-time MECS licensee, SNC Lavalin Group Inc., to perform engineering, procurement and construction of the sulfuric acid and power segments of the complex.  When operational in 2016, the facility will be one of the largest world-class phosphate fertilizer complexes, positioning Ma’aden as a significant global producer of fertilizers and other phosphate-based products. “We are proud to partner with Ma’aden and SNC on this landmark project and look forward to supporting Ma’aden in its endeavor to be a world-class minerals enterprise,” said Kirk Schall, vice president of Licensing, MECS, Inc.

February 4, 2014
- SNC-Lavalin in consortium with Sinopec Engineering Group (SEG), has signed a contract with Ma'aden in Saudi Arabia to provide engineering, procurement, construction, commissioning and start-up services for a three-line 15,150-metric-tonne-per-day sulphuric acid plant. Also included in the agreement are two 75-MW power plants that will recover heat generated by the acid plant operations. The total value of the contract is approximately USD$764 million with SNC-Lavalin's portion estimated at USD$500 million.The project was awarded as part of Ma'aden's Waad Al Shamal Phosphate Project, which involves the conversion of phosphate ore from the Al Khabra mine into various end products, primarily for the agricultural sector. The contract signing was formalized at a ceremony held in Turaif, Saudi Arabia today with the participation of the Saudi Royal Family, Government Ministers and various dignitaries.The sulphuric acid plant will use industry leading technology from MECS, Inc. (a wholly-owned subsidiary of DuPont) to produce acid and generate power through the efficient recovery of process waste heat. The project, scheduled to be operational in the fourth quarter of 2016, will be one of the largest complexes of its kind."We are honoured to be part of a project that will support Ma'aden in its mandate to develop its mineral resources and increase industrial development in the Northern Province and Al-Jouf areas of Saudi Arabia," said Dale Clarke, Executive Vice-President, SNC-Lavalin Group Inc.SNC-Lavalin is a longstanding leader in the sulphuric acid industry, having successfully installed more than 60 plants around the world over the past 25 years.
Maaden also signed the contract for building a phosphoric acid plant worth SR3,506 million ($935 million) to Hanwha Engineering & Construction Co. Ltd & Hanwha Saudi Contracting Co. Ltd. The phosphoric acid plant which will consist of three phosphoric acid lines when completed will have a production capacity of 1.5 million tons.
