A Disruptive and Sustainable Technology
Novaphos technology applies several prorietary innovations to well known carbo-thermal reduction and oxidation reactions in a continuous process that:
Uses low quality rock
The Novaphos process uses well know carbo-thermal reduction reactions to liberate phosphorus from phosphate rock with proprietary process conditions and techniques. The result is an efficient process that can use phosphate rock material containing 10-15% P2O5 and high levels of impurities. Our product acid is high-quality and low in impurities, and we avoid the production of large volume wastes like phospho-gypsum.
Our process starts by combining phosphate rock and, if needed for process chemistry, silica, together with a source of carbon, like pet coke and a binder. Phosphate raw materials can be ore, concentrates or tailings streams. These raw materials are ground, mixed and formed into a feed ball, which is then processed at high-temperature to trigger a reduction reaction in which phosphorus gas evolves. Following the reduction reactions, phosphorus is oxidized into phosphate gas and absorbed into water to make phosphoric acid. Following reduction, the processed balls are cooled and can be sold for use as construction aggregate as J-Rox.
