the process of extracting copper

Extraction - Copper information provided by Copper

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. The most abundant ores are chalcopyrite and bornite, which contain both copper and

Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

Copper mining and the copper extraction process explained

Most copper is refined from sulphide ores. The process includes the following stages: The copper ores are mechanically crushed and ground. The resulting mixture is treated using flotation with air injection and agitation to leave concentrates containing around 30% copper.

This is one way of extracting copper from low grade ores- which are less than 1% copper. Relatively, it is a cheap way of extracting copper. Select plants will absorb copper compounds through their roots, and the compounds become concentrated in the plant. When the plants are burned, the ash that is produced contains these copper compounds.
