QUEBEC – Commissioning of the pilot plant has begun at Focus Graphite's Lac Knife graphite project near Fermont. The pilot plant was designed and built and is being operated by SGS Canada in Lakefield, ON. The testing is expected to last four to six weeks.

The pilot plant tests are designed to confirm Phase 2 bench scale locked cycle tests, to assess the potential processing flowsheet, and to generate tailings for environmental evaluation. A range of graphite raw materials for customer assessment and upgrading will also be produced.

Focus said the average amount of graphite flake recovered from core samples in Phase 2 LCT increased to 92.2%, up from 84.7% in Phase 1. The portion of large flakes (larger than 80 mesh) in the concentrates ranged between 35% and 58%. Phase 2 testing also increased the carbon content of concentrates 4.6% to an average of 96.6% C.

The Lac Knife property is unique because of its high concentration of large, medium and small flake graphite, a characteristic that makes it cost effective, according to Focus. A technical report is posted at FocusGraphite.com.
