Located on the Atlantic coast, 20 km to the South-West of El Jadida, the Jorf Lasfar industrial complex started production in 1986. This new unit allowed OCP Group to double its phosphate processing capacity. The site was selected for its multiple advantages: nearness of the mining areas, availability of a deep water port, access to substantial water reserves and availability of land for future extensions.

This unit, which covers an area of 1,700 hectares, produces annually 2 million tons P₂O₅ in the form of phosphoric acid, requiring 7.7 million tons of phosphate rock mined out of Khouribga deposits, 2 million tons of sulphur and 0.5 million tons of ammonia. The energy requirements of the complex are met thanks to a 111 MW power station using recovered heat.

The Jorf Lasfar complex is composed of three entities, including the Maroc Phosphore III-IV unit which was created in 1986. With the construction in 1997 of the Emaphos plant, in partnership with Prayon (Belgium) and CFB (Germany), OCP Group entered a new era of diversification of its finished products by producing a high value added acid, i.e. purified phosphoric acid. Two years later, the commissioning of Imacid, a partnership with Indian Birla Group, enabled it to increase its phosphoric acid production capacity by 25% on the Jorf Lasfar site.

Maroc Phosphore III-IV has an annual production capacity of 1.4 million tons P₂O₅ of phosphoric acid, 850,000 tons of Di-Ammonium Phosphate (DAP) and 850,000 tons equivalent DAP of other fertilizers.

The sulphuric acid plant has 6 production units of 2,650 tons per day. The process used is double absorption Monsanto. The phosphoric acid plant is composed of 8 phosphate rock crushing units, 8 lines of 29% P₂O₅ phosphoric acid, 20 concentration units, 8 clarification units, 4 54% P₂O₅ acid filtration units, as well as a pre-treatment unit. Manufacturing is made according to the French Rhone-Poulenc process.
