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 2012 Americas School of Mines,2012 Americas School of Mines W Scott Dunbar University of British Columbia pwc,in pre‐production stripping over the period of 2009 through 2013.
