Estimating Mining Factors (Dilution and Ore Loss) in Open ...

 · The estimation of dilution and ore loss is therefore an essential part of any Ore Reserve estimate or mine schedule. Large open pit mines are driven by the economies of scale that are achieved at the cost of less selectivity in the discrimination of ore and waste.

Air quality and view degradations due to copper mining and ...

Green Valley, Arizona is a retirement community located near major open-pit copper mines. Mining and milling activities create dust, which degrades air quality, and mine dumps and tailings banks, which degrade the viewscape. Although the tailings banks are highly visible, this study found that consumer surplus lost from dust-polluted air is more than twice that from degradation of viewscape.

Contribution to Cost Estimation in Open Pit: Aggregates ...

It is assumed that the cost of mining ore is the same as that of mining waste. The cost of mining comprises drilling, blasting, Ioading and hauling, (in addition the cost of crushing). The cost of open pit mining can be assessed using the total ore and waste (T) mined daily (Table 1).

Long and Singer further studied Taylor''s rule in 2001 and calibrated it to 45 open pit copper mines. The open pit copper model proved to have a curve halfway between the 1998 gold-silver curve and Taylor''s Rule. This is due to base metal mines having less aggressive production rates than precious metal mines.
