Determining Stripping Ratio

The maximum allowable Stripping Ratio (SR max) defines break even stripping ratio (BESR) This represents the highest possible units of waste that can be handled If the SR exceeds the BESR then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in mining Get price
