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.
