Copper ore must be extracted using either open-pit or subterranean techniques. Open-pit mining is the most efficient technique for extracting huge quantities of material from low-grade resources close to the surface. Huge track-mounted drills prepare the ore for blasting, and the fragmented ore is transported to the ore-dressing facility by ...

As the ore quality is declining due to high consumption and over-mining in many areas, our copper ores still hold that quality and state we were providing before. There was a time a time when copper ores contained at least 2 to 3% copper in them now, it's left to only 1%, but we strive to mine those ores that are completely high-quality and ...
