Openpit mines that produce building materials and dimension stone are commonly referred to as quarries.

How Is Graphite Extracted? Sciencing

Drilling and blasting methods are used on hard rock ore to liberate largesized graphite flakes that are then crushed and ground before being subjected to flotation. The extracted graphite is brought to the surface by locomotives or, in developing countries, handpicked, shoveled and pulled in a cart and moved to the plant for further processing.
