What Is a Stripping Ratio? (with picture) wiseGEEK

09/05/2020· 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. As can be seen, when the ratio of unwanted

Stripping ratio and pit limit Basic Mining Techniques

The units for stripping ratios can vary and usually depends on the geological properties of the deposit and the commodity mined. It can be expressed in tonnes (t), or cubic meters (m 3).Usually for coal, cubic meters (m 3) or tonnes (t) are used.However, for hard rock mines where the geology is usually complex with the presence of various rock types, tonnage (t) is usually preferred.

Stripping Ratio Mineral Production Activities

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. Stripping ratio is influenced by the shape of the orebody and
