Stripping ratio Wikipedia

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 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

Break Even Analysis How to Calculate the Cut Off Grade

For conducting a mining project’s break even analysis, you first need to know about the operational expenses (OPEX).When the OPEX is known, you can calculate the mineral’s cut off grade, which is the break even grade, below which it is not economically viable to mine the ore.To find out how I come up with the cost price per tonne (OPEX) if a feasibility study isn’t available, I refer you

Determining Stripping Ratio Basic Mining Techniques

The maximum allowable Stripping Ratio (SR max) defines break even stripping ratio (BESR).This represents the highest possible units of waste that can be handled. If the SR exceeds the BESR then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in mining.
