Currently, the industry practice is to take mined phosphate concentrate and ship it to a phosphoric acid facility. There, it is combined with sulfuric acid and other ingredients to make ‘downstream’ phosphate-based fertilizers such as MAP and DAP. By working with both research and commercial organizations, Arianne is looking at ways to alter the traditional process and combine its concentrate with organic waste or other bacterias that would allow its phosphate concentrate to effectively be used in farming without the requirement of traditional acidulated fertilizer products.
“Although the work around the use of Arianne’s phosphate concentrate in these types of applications is early, the implications could be enormous,” said Brian Ostroff, Arianne Phosphate’s President. “For the agricultural industry, it could allow the farmer the ability to move away from acid-based processes and, by integrating with organic waste, allow for a more circular and environmentally-friendly process. Logistically, it would also allow Arianne to be less reliant on downstream facilities to purchase its phosphate and transform it into fertilizers.”
Due to the rare geological nature of its Lac à Paul deposit in Canada, Arianne will produce a high-purity, low-contaminant phosphate concentrate. By not having the deleterious elements found in most phosphate deposits globally, such as radioactive elements and heavy metals, the company believes its concentrate will be in high demand, not only by traditional fertilizer producers but also, those who are looking to target high purity agricultural and food applications such as organic fertilizers, food preservatives and animal feeds.
