Copper Mining & Processing: Everything You Need to Know

Tunnels are created underground until copper ore is found and extracted via drilling and blasting. How is Copper Processed? Copper ore must be crushed between extraction and production. Crushing and grinding breaks down the ore from boulder-sized to smaller pieces, making it easier to transport off-site.

Copper Ore Processing Methods

At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger concentrators has changed to such an extent that comparatively few of the machines in use at the beginning of the period remain in service today.
