Quarrying Granite extraction in Brazil primarily takes place through open-pit mining methods. Quarrying involves removing overburden (soil and rock cover) to access the granite deposits below. Once the granite is exposed, it is cut into blocks using diamond wire saws, chainsaws, or drill and blast methods, depending on the hardness and size of

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.
