Stripping Ratios, Pit Limits Cutoff Grade
For open pit mining the costs are $040/ton ore and a stripping cost of $050/ton of waste SR = (300 –040)/050 = 52 tons of waste/ ton of ore ie while the stripping ratio is less than 52 it is most economical to mine the deposit by Open pit mining is defined as the method of extracting any near surface ore deposit using one or more horizontal benches to extract the ore while dumping overburden and tailings (waste) at a Chapter Open Pit Mining2022年4月25日 The quantity of ore mined and waste rock (ie, overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rocktometal ratio (RMR), is an important metric for understanding mine wastes RocktoMetal Ratio: A Foundational Metric for Open pit mining results in two waste streams: waste rock which contains no economic quantity of minerals but which must be removed to gain access to the orebody, and tailings which are the pwc 2012 Americas School of Mines
