Stripping ratio Wikipedia OverviewSee also. 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

2016-4-4 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.

The stripping ratio (SR) refers to the amount of waste material that must be removed for a given amount of ore. The Instantaneous Stripping Ratio (ISR) is the stripping ratio for a given push back, where a tiny slice of material, i.e., ore and/or waste, is removed from a pit wall. This section presents the ISR calculation for a steeply pitching ...

2010-8-26 IFRIC 20 considers when and how to account separately for these two benefits arising from the stripping activity, as well as how to measure these benefits both initially and subsequently. IFRIC 20 only deals with waste removal costs that are incurred in surface mining activity during the production phase of the mine ('production stripping costs').

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 ...
