An educational presentation was made by Niall Weatherstone, Chief Advisor for Evaluation at Rio Tinto. The presentation clarified the technical and geological aspects of mining as well as significance of the stripping costs, especially in open pit mining. The main aspect of the presentation was treatment of waste and overburden.
pit gold mining project named "Coriorcco Gold", including a project description, an explanation of the main operational parameters, and an economic evaluation of the project. In the economic evaluation, variables as the breakeven cutoff grade (BCOG), stripping ratio
A strip ratio, or stripping ratio, is an important measurement related to the openpit mining process. It represents the amount of waste material, also known as overburden, that must be moved in ...
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.

The program will first determine the lowest Instantaneous stripping ratio in the calculation area. The program will then determine in which direction the stripping ratio increases the least. If mining were to start in the area of lowest stripping ratio and then move one grid node in the direction of least increasing stripping ratio, the ...
AVERAGE STRIP RATIO: Total waste divided by total ore within the ultimate pit. CUTOFF STRIPPING RATIO: Costs of mining a ton of ore and associated waste equals to net revenue from the ton of ore.
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 ...
