Manganese X Energy (TSXV: MN) is optimizing the flowsheet design for its Battery Hill manganese exploration property near Woodstock, New Brunswick. The updates will be included in the preliminary economic assessment of the project.
Changes to the flowsheet using phase three metallurgical leach optimization and purification results are expected to lead to lowered costs due to savings in reagent use to produce high grade battery products for the electric vehicle and energy back-up sectors.
Recent tests confirmed that >85% manganese leach extraction is possible when using a specific grind size. The metallurgical tests are being done by Kemetco.
Manganese X produced a technical report for Battery Hill last year that focuses on the metallurgical work being done. A contemporary, 43-101 compliant estimate is due in 2022. The historic estimate was 39 million tonnes at 9% manganese.
