摘要
Ore-TMRs, which are the total amount of overburden and rock to obtain metal ore, were estimated as a fundamental data to estimate the value of TMR (Total Materials Requirement) of metals. Ore-TMR of coal, iron, copper, zinc and tin are estimated 12.5, 5.1, 304, 34 and 95 representatively by statistic method based on hearing and investigation of practical mining sites. An approximation from the quality of crude ore and further approximation from the concentration of the metal in the crust were also proposed as and (ore-TMR) = 2.0/{100 x (quality of crude ore %)} (ore-TMR) = 2.0 x (concentration in the crust [ppm])(-2/3)).
