Phosphate acid technology to be commercialised

JDCPhosphate has announced that it is moving to commercialise its proprietary technology and changing its name to Novaphos.

The Novaphos technology, formerly called IHP, enables sustainable production of high-quality superphosphoric 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 quarter of 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 fully commercialise the Novaphos technology.

“Avenira is excited to see very strong results from Novaphos,” says Louis Calvarin, MD of Avenira.

“The recent Novaphos achievements represent very promising next-step development opportunities for our Wonarah project in Australia as well as at our Baobab project in Senegal and will factor in our strategic plans.”

Novaphos continues to run its demonstration plan using only low-quality phosphate rock tailings, containing an average of about 14% phosphate as P2O5, with high levels of silica and other impurities, including magnesium.

Avenira has exclusive licence rights to use the Novaphos technology in Australia and Senegal, where it has phosphate projects, for an extended period.
