Copper Statistics and Information - USGS

Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores.

The Stellar Origin of Copper by Ken Croswell

Furthermore, without iron, the neutrons can't make copper. Instead, Romano and Matteucci say, the Galaxy's first copper originated when its first stars exploded. Although such explosively synthesized copper makes up just a few percent of the copper on Earth, it accounts for most of the copper in the Galaxy's oldest stars--those with iron ...

How Is Copper Wire Made? | Synonym

The first step in making copper wire is what's known as the drawing process. Rods of copper are set on a machine, which will pull the rod through a drawing die. The end where the rod goes in the die is the same size as the rod, but the die narrows, which forces the diameter of the copper rod to shrink and pulls it out to a longer length.

Copper - Simple English Wikipedia, the free encyclopedia

The copper sulfide reacts with air to make copper metal and sulfur dioxide. Some copper sulfide reacts with the copper(I) oxide to make copper and sulfur dioxide. This makes impure copper. Copper is made pure by electrolyzing it. A thin sheet of pure copper is put on the cathode and a thick sheet of impure copper is put on the anode.
