how is copper mined and processed
Copper | Earth Sciences Museum | University of Waterloo
The amount of copper in the ground is relatively small and most of it occurs in lowgrade ores that have to be processed twice to extract the copper. This is why it is important to reuse as much copper as possible, and why about onethird of copper consumed in most industrial countries is recycled from scrap. Copper can be found as a pure metal as well as in combination with .

Copper is usually used in electrical equipment ( wiring and motors) and kitchen wares, but in order to obtain copper for these things, they are mined. Copper mining is usually done in openpits. To get the ore, boring machinery drills holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock. From the mining site, they are transported to the ...
How Copper Is Recycled
· Copper is considered to be the most used and reused metal resource in the world. Only about 12% of the world's known copper resources have been mined, but it is generally considered cheaper to recycle rather than mine new copper. Metal recycling provides the copper and copper alloy industry with the most economic copper feedstock.
copper processing | Definition, History, Facts | Britannica
copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a facecentred cubic crystal structure, and there is no critical temperature at which this crystal structure changes.
