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.

Silva et al. [28] studied the impact of changing the roller screening parameters in the screening efciency using fi discrete element method (DEM). One of the parameters studied was the reduction of the roll's diameter from 75.0 mm to 57.8 mm. Therefore, increasing the quantity of rolls for the same footprint.
