Selective Mining | Article about Selective Mining by The ...

Aug 13, 2010 · selective mining [si′lek·tiv ′mīn·iŋ] (mining engineering) A method of mining whereby ore of unwarranted high value is mined in such manner as to make the low-grade ore left in the mine incapable of future profitable extraction; in other words, the best ore is selected in order to make good mill returns, leaving the low-grade ore in the mine.

Optimal Selection of Selective Mining Unit (SMU) Size Abstract

The conventional definition of the selective mining unit (SMU) isthesmallestvolumeof material on which ore waste classification is determined[1]. The reality is more complex. It is impractical and impossible to freely select an SMU of ore in the midst of waste just as it is impossible to freely reject an SMU of waste in the midst of ore.

Selective methods generally, extract lower tonnages but allow greater selectivity between ore and waste, which minimises dilution and mining loses and ensures the maximum ore recovery. Typically, selective mining used for extracting the narrow vein-type reefs. Bulk mining methods are fully mechanized allowing the excavation of large volumes of ore.
