IHP Cost and Feedstock Availability Compared to the Wet Acid Process (WAP) Technology

  • All phosphate products are made from phosphate rock, a naturally occurring and limited resource that is highly variable, with many characteristics that affect its economic usability.
  • IHP, as a thermal process, has less restrictive requirements than WAP does with respect to rock chemistry and phosphorus concentration.
  • In many cases, IHP is able to process phosphate rock from reserves with ore body characteristics deemed to be of low quality or too dilute (low phosphorus concentration) to be economically viable for use in WAP.
  • IHP can unlock the value of billions of tons of low-grade phosphate rock reserves.
  • IHP uses low cost green petroleum coke as a primary process reactant instead of the more costly sulfur used in WAP.
