3D Blast Movement Monitoring BMT

3D Blast Movement Monitoring BMT

Pine Cove mine, located on the Newfoundland coast (Canada), was experiencing 20% dilution and lower mill feed grades because blast movement was entirely displacing ore blocks. By implementing blast monitoring, Anaconda reduced dilution to 5%, increased the mill grade and limited the waste going to the mill—generating $15,000 to $30,000 per blast.

the mine site, followed by additional crushing at the mill. The crushed ore is mixed with water and initial flotation reagents to form slurry. The ore is then ground in rod and ball mills. The slurry may also be ground in autogenous mills (a mill where the ore acts as the grinding medium) or semi-autogenous mills (steel balls are added to the ore).
