PHOSPHATE: Lac a Paul pilot test confirms 90% recovery

QUEBEC – Pilot-scale testing of ore from the Lac a Paul phosphate deposit in the Saguenay-Lac-St-Jean region has made a 39% P₂O₅ product with 90% recovery, according to project owner Arianne Phosphate of Saguenay, QC. The flowsheet relies on column flotation.

Results of the pilot test will be used in the Lac a Paul feasibility study to be completed this summer.

Arianne provided this excerpt from the report: "The metallurgical results demonstrate that the flowsheet with two cleaner columns and a cleaner scavenger column was the most promising circuit to meet the required apatite grade and recovery." Further that "The apatite concentrate produced met the requested quality targets (P₂O₅ greater than 38.5%) with a high yield recovery (greater than 90%)."

The complete report will be soon available on Arianne-Inc.com.
