Davy McKee Corporation (DMC) and the Florida Institute of Phosphate Research (FIPR) have demonstrated a practical process to thermally decompose phosphogypsum and produce sulfuric acid and a saleable, solid byproduct. The process would use the commercially proven DMC circular grate used in over 60 commercial grate designs. A successful phosphogypsum decomposition process will control the costs of sulfuric acid and reduce the impact of phosphogypsum deposits on the environment.
