A cave-to-mill study being conducted at the New Afton block caving operation demonstrated the potential for sensor-based ore sorting equipment to reject waste and improve the grade of feed to the mill. The lack of selectivity and potential for dilution entry associated with the block cave mining method results in many caving operations having to […]

This CEEC Medal-winning paper summarizes a comprehensive energy and cost study comparing an existing SAG mill based circuit at Huckleberry Mine  with two proposed circuits involving comminution technologies which are associated with energy efficiency: high pressure grinding rolls (HPGR) and high speed stirred mills. Results showed that the HPGR – ball mill circuit achieved a 21% reduction in […]
