Apatite refers to a group of phosphate minerals of variable composition.
Apatite is more than 41% phosphorus oxide (P2O5), making it a major source of phosphate (Quebec Department of Energy and Natural Resources).
2 Titaniferous magnetite (iron and titanium oxides), which needs to be separated from the ore to obtain the phosphate concentrate, would be stored separately for potential utilization.
A by-product: Titaniferous magnetite
"A by-product commonly associated with apatite deposits, titaniferous magnetite may be recovered during the concentration process.
For the moment, Mine Arnaud considers titaniferous magnetite as a mining waste since no economically viable market has yet been created for this by-product. However, given the potential environmental and economic benefits, Mine Arnaud is currently working to create a market to beneficiate this by-product rather than treating it solely as a mining waste.
Beneficiation of this by-product would help reduce the volume of accumulated tailings by nearly 20% and could generate interesting economic benefits for the Mine Arnaud project."
