Extracting copper. Extracting copper.

Extraction: An ore has to be changed chemically into the metal. This process is called reduction. How this is done, and how much it costs, depends upon the metal's reactivity (see reactivity properties). In general, the more reactive the metal, the harder it is to extract it from its ore.

Copper Mining and Production Processes Explained

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
