Stripping ratio - Wikipedia
Stripping ratio is defined as the tonnage of waste rock to be mined, divided by the tonnage of ore to be mined from the pit. Stripping ratio is influenced by the shape of the orebody and may vary considerably during the life of the mine. Except in rare cases, it increases with depth of the orebody below surface.

Ore Dilution & Recovery in Mining
Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ore thus left varies considerably ...
