What is operating stripping ratio in mining operation how do we calculate?

The operating stripping ratio in mining is the ratio of the volume of waste material that must be removed to extract a unit volume of ore. It is calculated by dividing the total volume of waste material by the total volume of ore produced. For example, if a mine produces 1,000 cubic meters of ore and requires the removal of 3,000 cubic meters of waste, the stripping ratio would be 3:1. This metric helps assess the economic viability of a mining operation, as higher ratiOS can indicate increased costs.
