Stripping Ratio Mineral Production Activities

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. The unit cost of mining may increase over the life of a pit due to increased stripping ratio and the longer
