Fertilizer International presents a global round-up of phosphate rock, phosphoric acid and finished phosphates projects.

Kevin De Bois of Prayon Technologies describes an innovative process for removing magnesium from phosphate rock. Increasingly, phosphoric acid producers are looking to consume low-grade phosphate rock as a feedstock due to the prohibitive costs of high-grade rock sources. This has potentially negative consequences as the presence of impurities such as magnesium can negatively affect both the phosphoric acid process and the quality of the acid produced.

CRU Events will convene the 2024 Phosphates International Conference & Exhibition in Warsaw at the Hilton Warsaw City Hotel, 26-28 February.

Brazil is a powerhouse agricultural economy, ranking as a top three global exporter of soybeans, corn and sugar. It is also the world’s number one producer and exporter of oranges and orange juice – as highlighted in our current issue (p18).

The cadmium and heavy metal content of sedimentary phosphates are of great concern. This has seen industry raw material consumption shift towards igneous phosphates or the blending of phosphate rocks from different sources. While rock blending can successfully reduce the heavy metal content of superphosphates, it needs to be accompanied by careful process adjustments, as Ian Hancock , Bradley Pulverizer’s vice president sales & operations, explains.

Ammonia production at Billingham in Teesside looks set to end, bringing to a close a history of production that dates back almost a century.

While phosphate fertilizer production represents the main slice of demand for elemental sulphur and sulphuric acid, sulphur fertilizers continue to be a growing sector of demand due to changes in the way that we use sulphur.

Leading companies such as Ballestra, Buss ChemTech, Elessent Clean Technologies (MECS) and Prayon Technologies are working together to solve the numerous production challenges facing the operators of integrated phosphate fertilizer production plants.

Despite being an age-old industry, the phosphate sector remains vibrant and driven by a passionate commitment to leaving behind a sustainable world for future generations. Tibaut Theys, general manager of Prayon Technologies, explains how the industry, by implementing more efficient production processes and promoting responsible fertilizer usage, is working urgently to reduce CO2 emissions, as well as striving to minimise its environmental footprint.

In this review article, Hatch’s Jayden Ladebruk, Lyndsay Tran, Amelia Parrenin, and Edward DeRose outline the wide range of phosphoric acid production technologies, and discuss how industry challenges are influencing the choice of phosphoric acid process.
