The Boundary Stripping Ratio In Ore Mining Home Ghana

Engin2503 mining engineering assignment help,break-even stripping ratio is the instantaneous stripping ratio when the cost of stripping the waste or overburden exactly equals the total amount of ore uncovered. In other words, it is the stripping ratio at which costs of mining the ore and waste are same as the revenue for that mine of ore.
