Plant throughput is constrained primarily by ore competency. The DFS called for the use of a single gearless SAG mill with 21,500 kW of installed power (at the time of t hestudy this was the highest power available for a gearless drive Constancia''sat altitude) and two ball mills .
Meadowbank Mine Process Plant Throughput Increase. plant design throughput as well as to evaluated the mill capacity increasing. The process plant team evaluated various expansion alternatives eventually deciding to install a secondary crusher, increased the SAG and Ball m ills .
The plant included single stage crushing, with conveyors that deliver the ore to a coarse ore bin. Coarse ore is ground in a two stage grinding circuit that comprises a SAG and ball mill. The ore/slurry from the grinding circuit is classified via the mill cyclones and the cyclone overflow undergoes differential flotation.
1 Over the past 15 years, minetomill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
