JDC’s Disruptive Technology

The Improved Hard Process (IHP) produces phosphoric acid more efficiently and less expensively than the existing wet acid and furnace acid processes.

  • Produces high-quality phosphoric acid directly.
  • As a thermal process, is able to economically process a broad range of phosphate rock chemistries and other phosphate bearing compositions.
  • Transforms dilute sources (such as phosphate tailings and phosphatic clay) into valuable sources of phosphorus
  • Transforms low quality phosphate reserves into valuable resources.
  • Enables relatively small scale projects to exploit small, and otherwise uneconomic, phosphate reserves.
  • Uses readily available, low cost petroleum coke as a primary process reactant instead of the volatile priced sulfur used in the wet acid process.
  • Reduces the level of beneficiation required on average (such as the reduction or elimination of flotation in many cases).
  • Has lower capital costs, a smaller capital footprint and a smaller environmental footprint than the wet acid and furnace acid processes.
  • IHP is synergistic with the wet acid process (WAP) in that IHP’s 70% acid can be blended with WAP’s 28% filter acid to make 45% acid suitable for MAP/DAP resulting in reduced WAP evaporation, purer WAP acid that require less nitrogen enhancers, lower mine cutoff grade, and longer plant and mine life.
  • It generates a salable aggregate co-product, J-Rox, rather than phosphogypsum, a high volume, highly regulated waste product.
