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.
