The process of mining copper begins with drilling and blasting. Large drilling rigs bore a carefully designed pattern of holes approximately 12 inches in diameter and 60 feet deep into the rock. The holes are filled with an explosive compound of fuel oil and ammonium nitrate which blasts thousands of tons of ore in a single detonation.

Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper.
