Overview Mining Project Arianne Phosphate Inc.

2019-12-10  The Lac à Paul project consists of the operation of an open-pit phosphate mine in the Saguenay-Lac-Saint-Jean region, located in Quebec, Canada. Every day, 55 000 tonnes of ore will be processed in order to produce 3 million tonnes of phosphate concentrate (apatite) per year. Approximately 1000 direct and indirect jobs will be created for the ...

Apatite Control of Phosphorus Release to Runoff from

2009-1-11  Phosphorus (P) in runoff can pose a water quality risk in phosphate mine reclamation areas. High dissolved P (DP) concentrations (about 0.4–3.0 mg L−1) in runoff from these areas and high equilibrium P concentrations for the soils led us to hypothesize that P release is controlled by dissolution of apatite rather than by desorption mechanisms. Objectives were to (a) verify via chemical ...

2019-3-1  The ability to mine for both phosphate and REE enables a more cost efficient mining practice. There are two processes of REE enrichment within apatite, the first is the substitution of REE 3+ and Na + for Ca 2+ within the apatite, the second is P 5+ substituted with REE 3+ and Si 4+ [ 39 ].
