Executive Summary
This section of the NI 43-101 Technical Report details the process flow sheet and plant design for the Renard Diamond Project. The design optimizes footprint and capital costs with a single process line for comminution and ore preparation, requiring two DMS circuits for concentration. The plant capacity is 2,160,000 tpa on a dry solids basis, with an estimated operating time of 6,833 hours per year.
The ore processing system liberates, concentrates, and recovers diamonds from 45 mm to 1mm using stage crushing to protect against diamond breakage. Recovery efficiency is expected to be not less than 97% by mass and 99% by value. The process includes primary jaw crushing, secondary cone crushing, and tertiary High Pressure Grinding Roll (HPGR) for re-crushing rejects. Final recovery utilizes magnetic separation, X-ray sorting, and hand sorting within a secure facility.
Processing Profile
- Crushing: Primary Jaw Crusher, Secondary Cone Crusher, HPGR
- Concentration: Dense Media Separation (DMS), Large Diamond Recovery (LDR)
- Sorting: Magnetic, X-ray, Laser Raman, UV, Hand Sorting
