Copper Mining and Processing: Processing of Copper…

Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant,...

Copper Extraction | Bruker

Since there are two types of copper ore: sulfide ores and oxide ores, different techniques are used for copper extraction. Each of these ores have both a different extraction and processing technique. Sulfide ores typically are extracted through open pit mining, which uses drilling and explosive blasting to obtain the copper.
