The future of phosphate production
In spite of changing patterns of demand, deglobalisation and environmental concerns, phosphate mining and acid-based processing are likely to be the mainstay of the industry for years to come.

PT Petrokimia Gresik detail an inventive redesign of their economiser, a critical component in sulphuric acid production, focusing on energy efficiency, decarbonisation, process optimisation, and equipment durability.
New supply is weighing on the market. In addition to increased exports in the second half of the year from upgrades and new refining projects from the Middle East, crushed lump sulphur is also again entering the market in higher quantities from both the FSU and the Middle East, and displacing granular product in some markets, notably Morocco and China.
Maria Mosquera, Editor of the Argus Sulphur Report and Liliana Minton, Editor of the Argus Sulphuric Acid Report at Argus Media assess price trends and the market outlook for sulphur and sulphuric acid.
Lithium ion battery production is driving major expansions in nickel and cobalt extraction, but lithium iron phosphate (LFP) battery use is growing rapidly.
All is not well with the Chinese economy. Growth has slowed to a fraction of what it was, only 0.8% in 2Q 2023, and has not bounced back as expected as covid lockdowns were eased. Exports and imports are both falling, debt has reached 300% of GDP, youth unemployment is running at 20%, and the property market is collapsing, with huge property developers like Evergrande and Country Garden only avoiding bankruptcy via government arranged loan restructurings. Consumer prices have fallen year on year, raising the spectre of deflation, and productivity growth has fallen from 4.5% year on year in 2006-7 to around 0.8% today. The yuan is trading at a 16-year low against the dollar.
As producers and regulators become increasingly concerned about the ‘circular economy’, there is increasing focus on regenerating waste sulphuric acid for re-use.
In this case study AGRU Kunststofftechnik reports on how a new condenser design, engineered by OMV and INWA AG using PFA sheets from AGRU, was implemented at OMV refinery in Austria to address maintenance problems due to corrosion of the wet sulphuric acid (WSA) condensers and the follow-up units.
A new burner design for the combustion of natural gas with either combustion air or pure oxygen as the oxidiser has been developed by CS Combustion Solutions. The new Oxijet®-Burner has been designed to perform both start-up and main operation functions with one burner.
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.
