First Phosphate Corp. (CSE:PHOS) has successfully transformed apatite concentrate to a high-quality, merchant-grade phosphoric acid (MGA) via its Central Prayon Process.
A 900-kilogram sample of apatite concentrate was previously produced at the First Phosphate pilot plant facilities at SGS Québec and sent to the facilities of Prayon Technologies SA in order to test its suitability for the production of battery-grade purified phosphoric acid (PPA).
Now, Prayon is assessing product quality and process feasibility through pilot testing of the First Phosphate rock concentrate to determine the optimal process parameters for MGA production.
An initial report on the pilot testing has been completed, and a final report is expected in the fourth quarter of 2023.
First Phosphate said that the phosphate rock concentrate can be considered a high-grade igneous rock with about 40.6% phosphorus pentoxide content. Furthermore, the general impurity content is low, especially chlorine (~630 parts per million) compared to other rock concentrates mined from the same region.
A full breakdown of the report can be found here.
