ore bin downstream and the unavailability of the rest of the
circuit to receive feed so material was processed in batch
mode. Once the ball mill and the rest of the downstream
circuit was handed over, the HPGR was run continuously.
Based on preliminary samples of ball mill feed, the par-
ticle size distribution (PSD) is comparable to the design
(P80 2.4 mm). Below pictures show HPGR feed and HPGR
screen product from site. Additional belt cuts and circuit
surveys are planned to validate the PSD of other streams,
evaluate screen performance, and identify improvement
opportunities.
CONCLUSION AND FUTURE WORK
First gold was poured at the Côté Gold mine in March
2024 and ramp up of the HPGR is ongoing. It is expected
that more operational data and learnings will be available
and shared by IMPC 2024.
