sector specific wastes generated during mining). The quantum of waste generation, however,, The ratio of overburden excavated to the amount of mineral removed is called the overburden ratio or stripping ratio. For example a stripping ratio of 4:1 means that 4 tonnes of waste rock are removed to extract one tonne of ore. Lower the ratio, the more productive the mine. Stripping ratio varies,Mining of Iron Ores – IspatGuru,14/03/2014· The total movement of ore and waste constitutes the mining process.
