Open-Pit Mining | Method and Process | Epiroc
Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

Innovations: Introduction to Copper: Mining & Extraction
El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is employed when the orebodies are extensive, low in grade, and relatively near the surface, where they can be quarried after removal of overburden. Chile also boasts the world's largest (in terms of output) open-pit copper mine, ndida.

Mining: making the move from open pit to underground
As a mine moves from open pit to underground, it's likely for the volume and grade of ore to change. This has implications for the mine infrastructure. "You need to consider the impact on processing," adds Bell. "A bulk open pit operation is likely to produce more tons of lower grade ore compared to an underground mine.".
