Copper Mining and Processing: Processing Copper Ores
The first steps of copper processing are the same for both ores: mining and transporting. Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted ...

Copper | Geoscience Australia
Copper is used widely in plumbing components and is a major component of alloys, many of which are harder, stronger and tougher than their individual constituent elements. In 1837 Charles Wheatstone and William Cooke patented the first electric telegraph, using copper wire. In 1876 Alexander Graham Bell was the first to use copper telephone wire.

Nickel / cobalt mining extraction procedures | Condorchem Envitech
The copper and nickel remain In solution. The copper is solvent extracted. The types of solvent used in this process are organic ones such as oximes, diethyldithiocarbamate, butyl acetates and ketoximes. These solvents form organometallic chelates with the metallic species in question, in this case copper, which are soluble in the organic phase.
