underground copper mine process

How underground mining works - Resolution CopperWhat you need to know about underground mining. The Resolution Copper deposit lies more than a mile beneath the surface. The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies. Here's how it.underground copper mine process,Underground Mining Methods of Copper - 911 MetallurgistApr 17, 2017 . The system of stoping as practiced was eminently satisfactory to supplement the steam-shovel operations without injuring the ore reserves of the property through a mixing of capping with ore. It had the advantage that all ore produced was absolutely free from waste, since both stopes and development.
