Mining Dilution

  • Mario E. Rossi

Dilution is a critical issue that affects many aspects in mining. It is generally due to the geometric characteristics of the ore body, the mining operation, the characteristics of geologic contacts, and the limitations of the mining equipment to recover material to the desired boundaries or contacts. There are three types of dilution that need to be considered at the time of mineral resource estimation. The dilution due to geologic contacts and the dilution due to the mixing of material types within a block are best tackled by geologists and resource estimators at the time of modeling. Operational dilution is generally planned for by the mining engineer at the time of developing a mine plan, but it also occurs unexpectedly, and is called unplanned dilution.
