After very positive bench test results that demonstrated a recovery of 91.4% of its phosphate-bearing apatite to a concentrate containing 40.2% P2O5 (phosphate), the Company decided to set up a pilot plant to process a large bulk sample. A 15-tonne bulk sample was crushed to a diameter of 20 mm and sent to SGS. Based on 15 separate crushed rock specimens, the bulk sample assayed 7.6% P2O5 (phosphate) and 6.9% TiO2 (titanium oxide).
The pilot plant optimises the Company’s metallurgical process for the production of a super high grade phosphate concentrate approaching 41% P2O5. The pilot plant has produced over 900 kilograms of apatite concentrate which have been sent to the facilities of Prayon SA (“Prayon”) in Belgium for the production of battery-grade purified phosphoric acid (“PPA”). The battery-grade PPA produced will then be sent to Company partners for homologation into their LFP cathode active material production processes. The pilot plant also produces valuable, marketable recoveries of ilmenite and magnetite.
The First Phosphate pilot plant uses fully solventless, environmentally friendly extraction methods. It is located at the facilities of SGS Canada Inc. (“SGS”) in Quebec City, Quebec, Canada.
