  • Stripping Ratios: What are They and Why are They Important

      Calculating stripping ratios At their most basic, strip ratios can be calculated by dividing overburden thickness by ore thickness For example, an overburden thickness of 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 ton of ore, for example, 15:1 as opposed to 3:2 Stripping ratio WikipediaIn coal mining: Choosing a mining method calculated with the aid of stripping ratios, which represent the amount of waste material that must be removed to extract a given amount of coal Stripping ratio s can also consider the selling price of coal, and a certain minimum profit can be added to the total cost of producing andStripping ratio mining BritannicaOverall stripping ratio (SRo) is the progressive or cumulative ratio of benches in consideration For instance the overall stripping ratio of two (2) benches will be the ratio of sum of waste to ore This is purely a physical ratio of total waste to total ore [Note: Equation 2 is expressed in tonnes (t), can also be expressed in volume (m3)]Stripping ratio and pit limit Basic Mining Techniques  Stripping ratio is a term that is derived from the mining industry and is used in reference to the openpit mining process The stripping ratio method of calculating the profitability of the mining procedure is commonly used in the ore or coal mining processWhat Is a Stripping Ratio?

      Stripping ratios increase with the quality of the ore being mined and cost factors related to beneficiation and transportation The economic stripping ratio varies widely from mine to mine, depending upon a number of factors In the case of direct shipping ores, it may be as high as 6:1 or 7:1 In the case of low grade ore , a stripping ratio of less than 15:1 is often considered as an   vii) Stripping Ratio The ratio is most commonly expressed as: Strip Ratio (SR) is the mass of waste to be mined to obtain one unit mass of ore Waste (tons) SR = Ore (tons) For example, a 3:1 stripping ratio means that mining one cubic meter of ore will require mining three cubic meters of waste rock • Syncrude Tar Sands: SR = 12 1 Surface mining planning and design of open pit mining
