The Novaphos technology, formerly called IHP, enables sustainable production of high-quality super-phosphoric acid (SPA) using low-quality phosphate rock without creating phosphogypsum waste.
Novaphos’ carbo-thermal reduction and oxidation process recovers phosphate from low-quality phosphate sources, including previously processed mine tailings,and avoids direct acidulation of phosphate rock, thereby minimizing the amount of waste and completely avoiding production of phosphogypsum. Instead of phosphogypsum, the Novaphos process co-produces solid balls from which phosphate has been extracted during processing, a commercially useful aggregate for construction and road building called J-Rox.
During the first calendar quarterof 2019, building on recent achievements at its demonstration plant in Fort Meade, Florida, Novaphos made additional improvements to its technology, further enhancing its efficiency and reliability. The Novaphos technology is now achieving phosphate yields of about 80%. Acid quality also continues to improve, with impurities at about 2% of SPA-equivalent acid,with strong potential for further improvement at commercial scale.
Novaphos has initiated a process of engagement with major phosphate producers and engineering companies to fullycommercialise the Novaphos technology.
“Avenira is excited to see the very strong results announced today by Novaphos” said Louis Calvarin, Avenira Managing Director. “The recent Novaphos achievements represent very promising next-step development opportunities for our Wonarahproject in Australia as well as at our Baobab project in Senegal, and will factor in our strategic plans.”
