The stages of mining: 5 lifecycle processes explained

Ore is natural rock that contains valuable minerals, typically metals and is extracted from the earth through mining and extracting the valuable metals or minerals. The grade of ore refers to the concentration of the valuable material it contains. Subsurface mining involves digging tunnels or shafts into the earth to reach buried ore deposits.
