Jun 30, 2019 · The stripping ratio method of calculating the profitability of the mining procedure is commonly used in the ore or coal mining process. In relation to its appliion in the mining of ore, the utility of the stripping ratio is the determination of the approximate ratio of waste material that must be moved in order to reach a certain ratio of ore.

mentioned ratio is ordinarily given in terms of m3 of waste per m3 of the related mineral. There are various kinds of SR classified as overall, instantaneous (operating), breakeven, and allowable. Overall Stripping Ratio (OSR) is the proportion of the whole volume of overburden in the OP to the total reserves of the mineral.
