The strip ratio (SR) is the simplest measure of mining efficiency. Defined as the weight of overburden (or waste ore) divided by the weight of oil sands ore, a strip ratio of 2 is considered high but feasible if the ore grade is high enough. A better measure of mining economics is the TV:BIP ratio.
In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore. For example, a 3:1 stripping ratio means that mining one tonne of ore wil...
6. Stripping ratio . The main factor in designing a n open pit mine, which largely determines the cost of mining, is the stripping ratio.. Stripping is the removal of waste rock from above and around the orebody. 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.
In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock. Stripping ratios are typically reduced to show the volume of waste removal required to extract one unit ...
May 09, 2020· 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 application 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.
