Copper Mining

Reliable Supply for Responsible Mining

Primary production of copper involves extracting copper from mined ores, typically sulfide ores. In the mining phase of copper extraction, industrial gases are used in several important ways that include enhanced safety and improved efficiency.

Explosives and Rock Blasting

Blasting is a required process to break up hard copper-bearing rock. Oxygen and ammonia are key components in the blasting process where ammonia is used to produce ammonium nitrate. Oxygen is used is used in some explosives for increased detonation.

Ventilation and Work Safety

Underground copper mining requires a proper ventilation system to deliver fresh air and remove harmful gases like carbon dioxide (CO₂), carbon monoxide (CO), methane or NOx. Nitrogen is used to create inert environments that may prevent fires or explosions. Gas detection systems and oxygen sensors ensure breathable air levels and monitor possible toxic atmospheres.

Inerting and Fire Suppression

Nitrogen and carbon dioxide are used in fire suppression systems in underground equipment rooms. These gases displace oxygen to extinguish fires without the risk of water damage.

Drilling Assistance

Under specific conditions, nitrogen may be used to drill through rock cuttings that may require special care to reduce corrosion and avoid reactions that can be caused with air.
